PS5 True 5.1 with Logitech Z906 Solved | NO More Audio Lag 

I have been reading and learning all about true 5.1 now. For about 4 days straight. By running a simple hdmi arc 5.1 dolby digital extractor, that costs $38 and using an optical cable from the audio system to the extractor and plugging hdmi from extractor to tv arc port I got full 5.1 native surround mix working. No decoding issues and very obvious difference in audio quality and directional audio. Bass response if way finer and more tuned at the dolby digital setting, and I honestly feel bad for the 5.1 stereo matrix users 😂 How to fix True 5.1 Surround: • Multichannel (Bypass) on TV • Dolby or Dolby Atmos on PS5 • HDMI CEC and eARC or ARC on TV • Decode light switched on, on the logitech control panel. • “AV Amplifier mode” on PS5 and set to 5.1 and adjusting speaker location. This all in combination is the only way to get real 5.1 surround on PS5. Any other work around if the decode light is not lit or the PS5 settings do not match these settings the decode could be lit but the sound didnt sound right. So make sure guys you do this correct the first time rather then the last time. Big diffirence in overall Quality and all directional audio being correct. If you have more then one HDMI ARC port on your TV I recommend you to plug in eARC to “hdmi extractor” and PS5 to HDMI ARC port for VRR / HDR support to still work at 4K 120hz. Without two ARC ports on the TV being used at once you will lose some PS5 functions.

I use Astro PS5 HDMI to Optical Adapter to passthrough my PS5 to my TV and Z906. On the Z906, the Dolby 5.1 Decode light is on, and the TV shows 4k 60 HDR simultaneously. No audio lag as well.

Good video!

Dude, that snake nest you got there is crazy, you need to do serious cable management right there.

Same position as you. My PS5 connects to my TV and the TV connects by Optical Audio to the speakers. The PS5 is set to DTS and the TV to auto (my choices are either Linear PCM or Auto). On auto, the decode light turns on and I get what sounds to me, like 5.1. My PC connects to the speakers by 6 channel audio from a dedicated sound card so all the lights go out I don't notice any audio lag. If there is, it's mere milliseconds that I don't pick up on

Hello mate My next question with witch component you connect this device Z906 5.1 ? And I'm want to buy same one thank you I'm waiting you replied ❤😊

I had genius 5.1 and in many games bass/center was swapped too and thats like 10 years ago

you should buy hdmi to hdmi + optical port convertor.. that is way better than using cinches

Will this speakers have lag on streaming netflix?

I have an extractor with an optical cable, the problem is the following: the ps5 lobby music is playing in 5.1, as soon as i play anything it switches to only the front 2 speakers. I tried dts and dolby. Lpcm cant transfer surround over optical.

Why doesn't it support HDR? So I'm losing HDR on my TV if I use this?

I get my working on a sony x900e tv using the optical out on the tv . Go to tv menu speaker and turn on audio system. Then go to the ps5 settings, sound ,audio output, HDMI device type and select AV amplifier . Then go to audio format priority and select Dolby or DTS . Hope this help

If it’s in bitstream then it’s still compressed audio. Unless you’re running LPCM via a sound card (which handles the signal) then you’re just sending compressed audio to all the speakers - not LPCM which would require 1.) A receiver ….or 2.) A sound card….also the lag is from the extra device you added. Let me put it to you this way - you are sending a direct audio (uncompressed) signal to the speakers, the speakers don’t know what to do with it and they’re running it bitstream instead, which is what Dolby Digital / DTS is which is why you’re locked on bitstream. This is why the manual says it only works via PC sound card, because that is what handles the audio processing.

Looks like you’ve solved a major problem! Can you tell me which 3.5mm cable adapters/splitters that I would need to order in order to do the left/right swap like you did??

How long are the speaker wires for the rear speakers? I want to use this as a HT. Thanks

Wait so does this allow you to get true dolby on the z906

HELLO, I watched all your video I need a hand because I have exactly the same stereo system and I also have an adapter like yours but the analog output is only optical (purchased on Amazon brand astro) and when I connect the optical cable it doesn't work 5.1 but it looks like double stereo can you help me???

I want to buy z906 and use this too. I hate ps5 ditch optical port

Just ordered one Hoping this wil work with my xbox and nvidea shield to z906 because my optical from tv to z906 does not give me the full 5.1 effect . The rear 2 speakers wil sound like they are under water. Hoping this will fix the problem

Hi so I've purchased a similar decoder for my fire TV. So I should set audio for pcm in order to get the effect?

what about bitstream dts ?

I assume this would work for Xbox Series X too? But as soon as you said no HDR, I'm out. Damn. If only it did support HDR.

Do a tutorial how to plug everything in correctly i cant make it work🤓💀

Hi, so i Orderd the z906 and i wanna know how to conect it to a lapptob ?

Yeah the lag is fine for movies but unacceptable for gaming

congratulations now you have lost the hdmi 2.1 features

He declares himself as gamer and doesn't know about HDMI 2.1 and 4K 120Hz VRR and ALLM... 🤦
