Dolby Pro Logic on Modern Receivers 

Please post here and let us know if your receiver works and with which format - Just include the brand, model and if a specific mode needs to be selected for surround to be enabled.

Just to add more details, Dolby prologic is producing only 4 channels (L, R, C and mono surround). Further Prologic 2 was released and it produce 5 channels with more precision

Hello, a little correction here, Dolby Stereo is also surround encoded, what happens is, Dolby Stereo is the commercial name that was used for theaters setups while Dolby Surround was the commercial name used for home theater setups, after that, the Original Dolby Surround was enhanced to support a center channel named Dolby Pro Logic, later came Dolby Pro logic II which sports a stereo surround channel, then Dolby Pro Logic IIx arrived with an stereo surround back channel for 7.1 setups, Dolby Pro Logic IIz was later introduced to sport a front high channels speakers and finally, the latest Dolby Surround upmixer released in 2014 along with Dolby Atmos to take advantage of the front high or top speakers. I've been building two Dolby Surround playlists here on RU-vid with some original encoded Dolby Surround videos and also games encoded in Dolby Surround and Dolby Pro Logic II, take a look!: Dolby Surround and Pro Logic II games: ru-vid.com/group/PLz7DJWigAF9cRbiUAciEtA7APHTv88Zsl Dolby Surround Mix: ru-vid.com/group/PLz7DJWigAF9cesBKSad3L9-KiP54yT8Lj

Can confirm, the test patterns worked perfectly streamed over RU-vid, through my TV, sending through eARC, to an audio extractor, to Toslink, into Logitech 5.1 speakers in Dolby Pro Logic II movie mode 😃

Wow, I knew this was going to be useful for my retro stuff but I didn't anticipate how useful it is for my current headphones on my PC! By messing with my settings, I can clearly hear how my headphones process "surround sound" and can dial things in to make it all sound better. Thanks!

I still have my first AV receiver that I bought back in the early '90s (Pioneer VSX-9900S) which provided my first Dolby Pro Logic surround experience at home. I've purchased many others since then (and still have those as well), but there was just something special about that one. Loads of analog inputs, too, and has been my go-to for phono listening as well as my Laserdisc player to this day.

been loving this audio series lately! after doing all my rgb mods it's time to move on to sound!

I've notice that when it comes to retro hardware, almost nobody prioritizes a good speaker setup to go with their fancy CRTs / PVMs / whatever. I realize maybe NES and what not aren't really going to take advantage but then you have games like Ocarina of Time that deserve at least a 5.1 surround system.

Im a year late bob but I just picked up a pioneer sx-316 and hooked it up to my crt. Its been really good for a system that's over 20 years old. Many swear by it. And for $20 at a local thrift store it was a no brainer to pick up. Appreciate this helpful video.

i do like seeing audio focused videos like this. always feels like it always takes a back seat to just graphics and sharper and sharper pixels.

Wow, this video is actually encoded in Dolby Pro-Logic 2!

Conkers Bad Fur Day N64 has dolby prologic and it sounds freaking amazing, the same with Metroid Prime 3, truly amazing stuff what a stereo encoded signal can do.

There are also some Dolby Stereo audio tracks on Blu-ray releases, mostly of older films. I know many Criterion releases with DTS-HD Master Audio 2.0 tracks recommend turning on Pro Logic. Shout! Factory also has a lot of DTS-HD MA 2.0 tracks with Dolby Stereo (particularly Escape from New York, Halloween II, Neon Genesis Evangelion: The Feature Film, and most of Studio Ghibli’s films from 1986 to 1994). Some Arrow releases also have Dolby Stereo. Many Fox/MGM releases have an alternate Dolby Stereo audio track alongside the 5.1 remix. Some releases such as The Secret of NIMH are Dolby Stereo-only. Lastly, many Bandai Namco Blu-ray releases explicitly state Dolby Surround. As mentioned, many Studio Ghibli Blu-rays also have Dolby Stereo tracks on the Blu-rays. They are guaranteed for the Dolby Stereo films in Japan, and more hit-or-miss in other releases.

This audio series is excellent! Pro logic was always a mystery to me in the old days. Terrible branding for an analog surround solution😂. Great work on this. Loved it

I've been waiting for a video about this! Thank you, Bob!

wow I've been looking for good info on this for years! Thanks Bob!

Really enjoying these sound videos being put out now. Not enough vids on good video game stereo stuff, since most people focus on head sets this day and age.

I have an old Onkyo receiver with Pro Logic decoding. It's amazing how well it sounds even when watching a VHS. The opening scene of Saving Private Ryan with Pro Logic surround activated, it is fairly immersive.

Denon 760H Dolby Surround. Worked with both a Wii and SNES Jr. through a RetroTink 5x over component and a Super NT over HDMI. Its nice to know that the Analogue console processes sound identically as a real SNES.

It's been a longtime. I remember that some movies back in the VHS days support Dolby Surround. There are a couple of games for Super Famicom and a handful of games for the original Playstation that I know support Dolby Sound: Tales Of Phantasia, Seiken Densetsu 3, Final Fantasy Tactics, Final Fantasy VIII and Final Fantasy IX.

This is some good content, I don't think that everyone knows these details. This even applies to modern consoles like the series X and allowing pass through for blurays for example and letting your receiver decide the proper audio formats.

Hearing true surround from my 2 channel stereo when played through my old-ish amp was pretty wild. I thought I wouldn't get to experience surround yet, even though I just recently set up some test speakers.

Dolby Pro Logic is awesome. I love playing GameCube and Wii games in a way I've never done before. On the movie side of things, I love playing around with listening to movies in their original "Dolby Stereo" tracks from the pre-digital days. For example, Star Wars' stereo track as opposed to the dedicated 5.1 one. It's also nice for watching RU-vid videos with a dedicated center channel for dialog.

Denon X4500H here, works perfectly with the tests in Dolby Surround mode. Confirmed using RU-vid app on the LG Oled with eARC and on Windows desktop. On Windows you will need to select stereo output as your speaker configuration, choosing any of the surround modes breaks compatibility. I'm not aware of any PC titles that ever supported pro logic as the PC always had its own surround sound formats so this isn't something you're likely to encounter while PC retro gaming.

Great video, thank you so much for putting this together

Also worth noting that some receivers will mix a surround signal into Dolby Headphones when using the headphones jack. It gives a pretty good simulation of surround sound when using headphones.

Looking forward to trying this tomorrow on my setup. I only hope RU-vid's audio compression doesn't compromise the test patterns! EDIT: Actually, just listening to them in 2 channel on laptop speakers is impressive, so I'm pretty sure it's good!

Centre Spread was primarily for use by people that didn’t actually have a centre speaker. Back then most TV’s were CRT so a centre speaker had to be specifically magnetically shielded as it was placed so close to the TV, otherwise the picture would suffer with colour distortion. Many people did not bother buying a specific speaker for this. The left and right hand speaker could usually be placed further away, so didn’t necessarily require shielding.

I tried this via my Yamaha rx-v681 and it decoded the audio nicely but I believe its only a pseudo surround sound as I think pro logic (II & x) has been dropped on most modern amps, I also tested it on my M1 MacBook Pro and amazingly it gives a great virtualisation of having surround speakers, the speaker setup in this Mac constantly shocks me! Incidentally on my old amp I used to use that surround test from Rogue Leader to impress my friends back in the day 😆

While collecting my crt horde past couple of years I couldn't help but pick up some receivers/vhs ect... usually found at same dump spots. Will definitely look into this and report back my findings.

as someone with a Classic Pro Logic Receiver this was a pretty cool Call Back and was actually the only way i figured out to clump the 2 Back Speakers together for that proper Listening Position of old N64 Games can't wait to see more also this does work with Rare Replays Jet Force Gemini and Conkers Bad Fur Day as both of those games utilized Dolby Surround so thats extremely cool to see

This is an excellent resource.

They all work on sonos beam with one sl’s through eARC on C9 Oled. This was the most channel accurate video on youtube. Plenty of others play rear as front and sometimes no sub tone. Idk what u did but it worked 100% flawlessly for proper channels

I've wanted to know about thiis for some time but the mot I could find were some tech forum posts saying that pro logic encoded sources should theoretically work correctly in modern Pro Logic, Neural X and Auro 3D modes. It's really nice to have a way to actually test it. Now we need something similar for DTS Interactive that a handful of old games support. (such as some of the SSX games)

Okay, so I tried the test videos on my 5.2.4 Atmos setup. And it worked correctly. Both Using Atmos Dsur and DTS Neural:X. It ignored all four ceiling speakers. In both tests, it correctly isolated, Left, Right, Center, and playing in both surround speakers. The Tie Fighter Sound properly circled all five speakers. It did not artificially try to pipe the left, right or surround signals into the ceiling speakers. I also tested it in the 7.1 setup in my bedroom which has an older receiver. The first test came out okay. The Surround channel came out of all four rear speakers equally. But the second test was a bit wonky when I played it using straight Pro Logic. I seemed to get at least a little sound out of each speaker at all times. This applied for all the speakers. When it was that speaker's "turn" it did play the white noise the loudest. The surround "turn" played from all four speakers equally. But then I switched to Pro Logic II and it stopped doing that. Each channel was discreet and it ignored the surround back speakers completely. The Tie Fighter circling seemed to play correctly. I could hear no sound from the rear speakers when the sound was in the front and vice versa. Because of the placement, I could not tell if it was the same sound in the side surround and rear surround speakers or it was traveling from one to the other. When I just listened to it from my bed, I could hear the circling. But it was not as obvious as in my living room. Both tests were run using HDMI and ARC.

Even if you have only two speakers, you can still use Dolby Surround/Pro Logic in games and other media; it'll just cause sounds behind you to sound like they're in your head. It works great for headphones, and is maybe just passable for two speakers. Of course, I will eventually have more speakers and an amp someday! 🙂

Bob, you rule. Happy Holidays.

Thanks for these vids. I still have my old Onkyo which supports both digital and analog surround modes in 6.1. I know my new Yamaha TSR 700 doesn't support any of the old surround pro logic formats. Dolby surround test works great in neo6 cinema mode as does pro logic test. Pro logic II test sounds freaky but in a good way!

Just about 4 years ago I had our 1996 Kenwood pro logic system in our living and it was still pretty immersive even though Im so used to my modern setup with new dolby surround and atmos

Even if it can't do true surround sound, it still sounds better than TV speakers (which is fine by me.) Speaking of which, I ran this test on my 43" LG 4K TV with a Yamaha ATS-1050 soundbar hooked via Toslink. The surround effects aren't too bad.

be aware that in 2014, Dolby released a new matrix decoder under the "Dolby Surround" brand, which is similar to but not exactly the same as the previous Dolby pro logic ii decoder, and as such, sound systems made after this date (primarily ones with Atmos capability) which simply mention "dolby surround" and do not carry the pro logic or pro logic II branding may produce output inconsistent with the original intentions of the mix.

Surround is in the mix. I hear all the effects in the tests with only two speakers and a class D amp with tube preamp. My speakers are cross streamed and tilted up 7 degrees. The TV and speakers are at a 30 degree angle out from the back wall, and the seating area is parallel to the sound stage. This makes full 360 surround sound with Elac DBR62 speakers. AV receivers just separate the effects and send each to a separate amp, then to a single speaker for each part of the mix. Then you can adjust the volume of each speaker to get the surround mix you want. With two speakers, you only hear surround when facing the sound stage. With 5.1 and multiple speakers you hear surround always, if surround is in the mix. A sub is not needed if your speakers and amp can play low and loud enough. Mine go 30 to 30khz, so full enough range. Great for movies and music. Sound even comes from other rooms sometimes... My room is on the small side. Larger rooms will benefit from more speakers. Thanks for the test. They really worked even on my two channel system!

Thanks for the video, I was wondering how well modern receivers handle this legacy stuff.

So I have a Vizio M512 sound bar and it turns out I have to use either the EQ Movie or EQ Game mode. Normally I would use EQ direct for modern 5.1 and Atmos. I can still hear some sound coming off the front speakers faintly for rear channel. Don’t remember if it was always like this using my older Pro Logic systems.

I recently got a surround sound set up and I have it hooked up directly to my PCs motherboard audio, and one thing I realized was that asrock had a partnership with creative so you can use their sound blaster connect software on certain models of asrock motherboards, mine was supported and it had a surround sound virtualizer feature and so I decided to try that with the prologic tests. It passed all of them. I am super excited at that fact, I can't believe it passed them all. In case you're curious what I did was I set the sound mode to movie mode and turned off all of the enhancements except for the surround sound and bass which I couldn't change.

My PC is connected to an HDMI receiver, and to get it to enable (and decode properly) Prologic decoding modes, I had to set windows ouput to stereo ; if set to 5.1 the surround decode button did nothing. Yamaha HTR-2067

TIL I learned my JBL Bar 9.1 Soundbar can properly decode Dolby Surround. I gotta bring back my Pioneer CLD-D704 back into my entertainment center in my office. Having a fully set up 7.1 home theater and the Bar 9.1 for atmos in my home office has paid off.

Rogue Squadron II and III are good for testing dolby pro logic as they have tie fighter surround sound tests in the extras menu

Wow I was listening to the test patterns on my pc with my G560 speakers and I could hear surround sound.

Hello. Word of advice, if you have issues and use RU-vid on your smart TV. Change your TVs audio output to "pass through" mode. I found the test pattern audio to only work in this mode. My TV is a 2022 Samsung Frame, other options like Dolby digital plus did not work. This was over HDMI arch to my Yamaha RX-A550 receiver.

I have a Denon AVR-3806 with 7.1 speakers connected to my PC via HDMI through the GPU. For your video, I set the Windows speaker config to stereo, then set the AVR to ProLogic IIx. Your segment transitions appear hit the surround speakers and the surround test worked properly in all speakers. The requirements for decoding ProLogic are simple: 1. The content must have been mastered for ProLogic, 2. The output (from game console, computer, video player, etc.) must be 2-channel/stereo, 3. The audio playback device must be able to decode the ProLogic. I've not tested GC/Wii emulation, but ProLogic from SNES emulation works. Set Windows to output stereo, enable ProLogic in the game, set AVR to use a ProLogic mode. Fatal Fury Special on SNES is a good demo. I played Metroid Prime and Resident Evil 4 in ProLogic on GC and Wii consoles years ago, worked very well.

Used the Pro Logic II Movie setting on my Logitech z5500 for the rear effects to come through with the last three tests, otherwise left/right fronts and center work through sound card just fine on a separate computer(Audigy2 ZS had DD/DTS decoding, so it could have explained why I heard a center channel and not the rears). DD PL II Movie audio came through a different computer connected to an HDMI switch, which then got filtered through LG C7 ARC via optical to the speakers with decoding. Enjoyed the Pro Logic II stuff at the end and it reminded me of the PS2 days. OG Xbox had Dolby Digital encoding and it was nice; seemed ahead of its time because no one else was doing it. I remember hearing QSound in arcade games and it's just enhanced stereo, that was enjoyable. These days, I'm fine with good old DD/DTS on the 360/One/One X/Series X so I don't think I'll be splurging on Atmos next. The Switch has some weird surround option that I think only works if you have a receiver that works with PCM surround or whatever it is. That Logitech Z5500 is a beast and still works, since buying it around ~2005(?). Before that it was a Klipsch ProMedia 5.1 and purchased the decoder separately. I love this surround sound stuff.

I'm wondering if you have any Dolby Stereo and Dolby Surround tests. I thought those were the format and Dolby Pro Logic was the decoder. Also, I'm curious about Pro Logic IIz with its height channels. We're those magic'd in or part of the mix with weird phase adjustments?

Thanjs Bob!. 😁👍

I remember my first surround was a creative 5.1 kit from 1994 or so and I drove it with a sound blaster using 2 RCAs as it was all we got (more or less)

2:55 Center Spread is really for listening to music in Surround sound, because typically the decoder will collapse the stereo signal of music all to the center speaker and you'll lose your stereo imaging, strange that that was enabled by default in your AVR.

Just out of curiosity, does the Pro Logic II/Surround (2014) technology when fed a stereo signal steer any dialogue (if called for) to the center when upmixing to however many channels setup (as most movies that are natively in 5.1/Atmos are) or do they leave the stereo sound (optional with dialogue) unaffected with other sound channels coming to play and having the dialogue be on the fronts (Left, Center, Right)?

I have an old but very high quality Sony STR-DB930 AV receiver. It has the original ProLogic but not ProLogic II. The first two tests work exactly as you expect with 4 channels very clearly. As you might expect, the ProLogic II test at the end works in only 4 channels with the sound for the rear speakers just coming through as a single mono sound played through both speakers.

Hey Bob, DTS Neural X is an upmixer so it make sense you'd get surround from Dolby content there too. I'm a huge fan of using it in my home theater to get sound from my front wides (in 9.2.4) from things like Dolby Atmos content that's usually locked to a 7 channel bed layer. In retro gaming, I find that it really helps with immersion since it does a fantastic job with some of these older surround formats too.

I am a big fan of Pro Logic. I know if you ever want to compress video captures using Handbrake, and happen to have ac3 5.1 as audio, it will often default to re-encoding the output for Pro Logic since it plays much nicer with most devices and web streaming sites. I did a video playthrough of Resistance: Fall of Man this way and was really happy with the results.

Thanks this definitely helped with both Ocarina of Time and Majora's Mask on My N64.

My favorite surround test was always the Halo 2 Limited Edition DVD test. Always got a good laugh out of it. 🤣

art of fighting 1 for the snes has this "stereo exp" and its veeeery good! in a 2 chanel setup, kind of works like q sound, but in 5.1 its amazing

Its funny you mention that "Center Spread Feature" about Pro Logic, on Pro Logic II Music mode for a lot of recievers it seems to USE that function automatically with Music mode, and NOT for Movie Mode which is interesting.

So I have a Vizio M51ax-J6 and I’ve used game mode for PS2 & GameCube games. Does it work out in the same matter as Dolby Pro Logic II? I ask because when I click on info, it reads as LPCM. When I go to my TV settings & set the audio output as pass through, when I click on info on my Vizio remote, it says nothing. If it’s saying nothing, is that actually Dolby Pro Logic II or not?

Thankfully my TV / Surround sound does all this switching automatically. the TV passes it right through to the surround and the surround has no trouble detecting it. its wild to play things like DOnkeyKnong N64 in surround sound, o r Starfox Adventures Dinosaur Planet. there's so many good retro games that have surround baked in.

Thank you

my onkyo have wierd bug with dolby surround and atmos that makes it really long time to kick in (to detect dolby signal) so I use dts neo 6 for stereo and it works like prologic :)

lol, I am using a jvc receiver from the 90s or early 2000s and it does Pro Logic native. interestingly a lot of newer surround formats seem to work pretty well too in sound tests...

My Yamaha rx-385 works phenomenally, however make sure to select the one for either game/music/movie for whatever your listening to. Also in windows 10-11, you need to set the configuration to actually setting 5.1/7.1/atmos/dts-x as it might not be available initially.

I have a JBL 9.1, I converted the analogue signal to digital and connected it through a toslink cable, I saw that its optical input supports Dolby Digital, does that include Pro Logic II? There are no internal menus for me to check this, when I tested a game that I knew used Dolby Digital it appeared on the soundbar's display, while testing something Pro Logic II had nothing appearing on the display.

yes I played surround sound by my cassette walkman too, dolby surrond pro logic 4.1 or pro logic2 5.1 or pro logic2x 6.1, 7.1 or pro logic2z 9.1 or DTS NEO6 6.1 needed and surround recording of the audio also needed.

Bang Olufsen AV 9000 : Pro Logic Mode (5 Speakers) : Sourround Test OK, Pro Logic Test OK, Pro Logic II so-so (as this is a branded Pro Logic receiver and not II it may be normal !)

Where is this Wiki that he is referring to? I would love to read though that and find out more details on all of the various surround sound formats, if possible. Great video!

Just wondering if (for convenience sake) these Pro Logic test sounds could be burned as an audio CD and played back through a PS1? My amp (Sony STR DN-1080) has two main modes "2CH/multi" which has stereo/direct/multi stereo modes and "movie" which has the surround modes such as Dolby Surround and Neural X Regarding Dolby Surround, it is a mode that will take stereo or whatever and upmix it to make fake surround sound, however the manual also says this: "This upmixer is a new and enhanced replacement for the Dolby Pro Logic II technology." I'm not clear if it will decode Pro Logic as it should do, or if it will just take the stereo channels and do it's upmix/fake surround thing to it

Does Dolby Surround work with Atmos soundbars?

Do you have these clips available for Dolby Pro Logic with video?

worked with my denon 3810 as expected. I actually prefer dts neo:6 to "decode" dpl(2) sound :) back channel is a bit more separated in my opinion.

I thought YT didn't support surround sound. :O But lo, and, indeed, behold, or, equivalent for hearing, that Tie fighter was circling rather menacingly. I have a self refurbished Yamaha RX-V595RDS, not exactly modern, about 2002 vintage, but works well with those patterns.

Tested out on my Yamaha RX-V383 (all settings are stock, DSP level was set to zero for CinemaDSP): OG Dolby Surround (you're not going find this is a post 1990s decoder soooooo) -- DPL: LCRS decoded with no bleed and mono surround DPLII Movie: LCRS decoded with no bleed and mono surround DPLII Music: L and R has some bleed into surrounds, surrounds were mono CinemaDSP Standard: LCR Decoded with no bleed.

For those who prefer the original Dolby Surround and Pro-Logic without "steering" this may be a turn-off.

Can you pass Dolby Surround through HDMI when using a 2X-Mini? I assume you need to force Dolby Surround decoding...

I have a JBL 5.1.2 Dolby Atmos compatible Sound bar, it doesn't have any surround configurable options aside from a basic Bass volume and calibration mode. My PS2 is connected to a Retrotink 2X Pro, can I get any Pro Logic 2 surround out of it?

I've been struggling with surround lately. I figured out how to get my amp working with retro stuff and Dolby surround. The PS3 just wouldn't work with a Ratchet and Clank game. No matter what I did, surround sound wouldn't work. Only the rear channels would output. I had to disable all the surround formats in the PS3 settings except for the base Dolby one and then it worked.

What database is shown at 9:24? (EDIT: Is this MobyGames?)

If in my laptop I play a Dolby surround or pro logic II game in an emulator (let's say Ocarina of time or Majora's mask) and I hook it up to the TV vía HDMI and then audio setup vía either HDMI eARC or optical... Will it decode?

useing dolhpin (gamecube/wii) emulator dolby pro logic 1 and 2 wrok amazing even on newer hardware im useing a 5.1 atmos system and love it

Just FYI, todays Soundbars don't seem to be able to decode Dolby Surround or Pro Logic II (even with dedicated rear speakers), the decoders are probably AVR exclusive.

Wow, EuroTrip on VHS?? That movie is from 2004. I completely forgot how long VHS went on for. Great video and topic though. I've always wanted a surround sound setup, but I feel like it dominates the space you want to use. It sure would be cool to go back to GameCube games like Metroid Prime and hear it in surround sound. Back then, I didn't really understand Dolby Pro Logic back then. I thought surround sound had to come from optical or digital coax rca, so I thought it was just a way to widen stereo to simulate surround sound. I think I enabled it in my games and assumed it was fine because I could still hear the game.

Whoa played this video on my phone (galaxy S10) And it seems to decode the prologic tests correctly, it somehow creates virtual speaker sounds around it Even more impressive (to me) than playing a 4k/HDR+Atmos file 😆

What I am struggling with is getting Surround Sound out of RetroArch.

I've heard that the EARS mode on your NAD surround receiver is on of the best surround modes that are better than Dolby Pro Logic and Pro Logic II. The same for Lexicon and Harmon Kardon's Logic 7 Surround mode. On the newest receivers that had Dolby Atmos, they have the new Dolby Surround mode which is a upmixer so you can use all of your Dolby Atmos speakers.

Fyi, Dolby Stereo IS Dolby Surround/Pro Logic, it was just what it was called when it was first a thing in theaters. Otherwise great video!

NEO:6 is basically DTS' version of Pro Logic II.

Dang, the Galaxy S20 FE pass the surround test on its built-in speakers. Didn't expect that result.

Works on my Sound Blaster X G6

An old tablet working as a youtube player -> hdmi -> tv -> spdif -> old onkyo receiver -> 4.1 speakers setup Works fine in PLII music and movie modes. it's sad it's not used in every movie or series that comes with "stereo" sound by default, but with the PLII it sometimes just works pretty by an accident, or tat least the surround speakers are not just muted. Or maybe stuff like movie trailers could be uploaded to RU-vid using PLII or a similar encoding.

Yamaha had beam speaker sound bars that turned every single input you fed it to PRO LOGIC 2 then beamed it around the room after a mic calibration i owned one the yas 2700 and it was amazing. with added rears it would have ben even better. it would take any stereo or surround channel format dp2 edit it then use Yamaha processing to beam a sound bubble around the listening position. there new ones do this in DTX VIRTUAL X NOW

Does not work the PS5 RU-vid app but good with my Chromecast 4k ultra.

Dolby Stereo is Dolby Surround, but the theatrical name. Why did you say not to use that?

Testing Resident Evil 2 on N64 which uses Dolby Surround and it works really good. It's awesome to test old games with those capabilities. 🙂
