DJI Osmo Action 4 owners - Watch this BEFORE you buy a microphone! 

Thanks Andreas! Really appreciate your help! It always seems like DJI slips in audio improvements in firmware updates under the radar (I never see them listed in the notes) but hopefully the next FW push resolves these issues!

Lol, thanks! I try my best because I truly appreciate someone taking the time to comment, but some do fall through the cracks! Thanks for the sub!

Thanks Dave! Frustrating for sure when you buy a mic that works great with the Action 3 and then when you upgrade to the Action 4, it doesn't function as intended. The Deity V-Mic D4 is a great little on camera mic. I think Ian has one too. The work around is that the mic also comes with a USB-C to TRRS (smart sensing) cable that works as intended with an adapter (like the BOYA BY-K4) but that totally defeats the purpose of a single USB-C cable lol! It would be one thing if this issue cropped up with budget mics from smaller unknown brands, but Deity and Sennheiser make great products... Fingers crossed DJI comes through in the end!

Thanks Alex! Always feels like a work in progress but I think I was ready for a change!

Ha, sounds like a video I'll have to sneak in!

Struggling with same. Have you found a solution? My voice starts crackling a lot.

@@RecluseRider not yet. I plan to make a vlog and share it with DJI support

Thanks for your comment! And sorry to hear the new Wireless PROs are experiencing issues with the Action 4! I'm glad you found a workaround, but it must be super frustrating as the whole point of a USB-C audio input is to have a single direct connection! I'm still hopeful that DJI will figure it out especially if popular RODE systems aren't working seamlessly.

@@WayneRECs Sadly I recorded 51 Gigs of material yesterday and all of them ruined by clipping audio levels. I suspect that the autogain feature only works with the usbc to usbc connection. Can't be sure but I've gotten 99% clean audio with the autogain using the direct usbc cable. Now almost all my audio from yesterday is ruined when I used the boya adapter and 3.5mm rode cable. Voice understandable but that's not good enough for me. I have been on a mission to get clean vehicle sound + helmet audio in my videos for more than a year now. This RODE set with the autogain is the closest to a plug and play setup I have had so far but these issues are a big problem. I will make a video about this setup after I'm confident that its reliable and works well.

Thanks for sharing! Great hearing viable motovlogging solutions from those with real use experience!

Thanks for sharing! Good to know that you're having this issue with the Wireless GO II in usb output! Here's hoping DJI and solve this for everyone!

Glad to hear you figured out a solution! What wireless set are you using? It took me a while to figure out how to consistently replicate the bug consistently and figured it would help others who might be having the same frustrations for what seems like random mic recognition issues. Hopefully, DJI can address this in the next firmware update!

🤔 I assume that’s why musicians and and film sets do an audio check Pryor to to the show or filming, but I could be wrong 🤷‍♂️😝✌️

Chris! Thanks for stopping by! Reliability issues are frustrating for sure across the board! Especially in situations where there is little to no time prior to shooting (which is how I think a lot of Action Cams are used)!

@@WayneRECs yes all run and gun 🔫 situations shame when mic stops randomly

@rawbsworld6604 haha yes good habits are helpfull I just do run and gun stuff messing around with kites I'm just a kook learning what I can

@@christomo hahaha ain’t we all, 👍

Thanks! Like they say, the squeaky wheel gets the grease! I hope other OA4 folks find this so 1) it's validating if they are having an issue and 2) they can contribute their experience so there's a wider understanding of how it can be fixed. I'm confident DJI will address this, though it might be a fix that they don't docu in their firmware notes (as I find they rarely include any audio related updates lol)

Saramonic usb c to trs with rode videomic go 2 seems to be fine

Awesome! Thanks for sharing!

My Comica VM10 Pro seems to be working fine when connect vis USB-C

I have the Sennheiser XS lav which now seems to work fine with the latest Action 4 update.

@@WayneRECs Great, will try that out. Thanks Wayne, and keep up making these wonderful videos!

What mic are you currently using with the BY-K4? Any recommendation for a mic, for creatiing e-biking videos with a OA4 with a chest mount and a lav mic? Be it in the city or nature. What lav mic would you recommend? I'm a beginner to audio, but looking for some street ambience and a clear voice recording.

Have you tried out this setup yet? I'm interested in doing the same.

yeah, same with mine too, we have to unplug it hear any sound from the cam

Hey Rawb! So I think it's a camera/firmware issue. Swapping USB-C cables with the Deity still produces the same behavior and my XS lav functions as expected with my Action 3. The one workaround is to connect the Deity V-Mic D4 (using the included USB-C to 3.5mm cable) to an adapter like the BOYA BY-K4 then into the Action 4. In this set up, everything starts up and works like you'd expect, except now there are additional cables and connections which kinda defeats the purpose of a USB-C input lol!

Ya 👍 wasn’t Didn’t recall if you mentioned using a different mic/cable of the same brand, thanks for the clarification 👍🤗

i have the BY-K7 and doest recognize the mic pls help I have lavalier II

Hey there! DJI has updated the Action 4 firmware since launch and replaced the Mic Icon with the Green Bar that now indicates the audio level when an external mic is connected. Activating the PRO mode will allow you to adjust the Gain level of that mic.

@@WayneRECsthank you 👍👍👍👍

Ha! One of my personal favorite workflows!

This would definitely work if I'm not motovlogging. But if I'm, then one of my biggest problems with this workflows is that on longer rides, I may not record for hours at end, and then if audio recorder is within my helmet, turning off the audio recording each time gets super frustrating and takes my attention and focus away from the joy of riding. If I keep recording, well I may have 12 hours of continuous audio to sync with barely 60 minutes of fragmented video. And if I don't have the device on my helmet and rather go for the recorder/controller outside of my helmet, then on each stop, there are cables to manage before taking off the helmet and parking the bike.

Hey Jhay! Unfortunately, I don't have a FULAIM X5 system.

@@WayneRECs i've recently bought Osmo Action Camera 4.. thinking to buy this Fulaim X5 on amazon.. i'm from philippines by the way :)

@ItsSKYYo just released a video testing out the Fulaim X5 for the Action 4. Check it out here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TqyDMDFNB3Q.htmlsi=fOswClJ0kV59WeI8

With my limited sample size, I don't really know how many mics are affected, but the bug is super frustrating for sure. Especially if you have no clue as to why your mic works sometimes but not others.

Our conversation prompted me to make this video! I too was hoping it would have been resolved with the 9/7 firmware update, but here's hoping DJI figures it out on the next one! Glad you found an alternative in the meantime!

Hi! If you're looking to attach a mic to an Action 4 using the included stock plastic cage, check out the Ulanzi OA-19. I did a video on it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZWLEIoYNjUM.html

The same goes for me when motovloging. I use Boya BY-K4 adapter + my trs lav mic. Yesterday i had updated the firmware. Still got a problem with quick capture video. You need to turn on the camera first, then record. Very frustrated.

@momengadget yea and tech support suggests using the dji wireless mic, but can't understand why it won't work on a helmet. Basically dji is not acknowledging the issue.

Maybe we need the original audio adapter from DJI itself. Who has tried it?. Please share the outcome. Thanks.

@@zulmomen I have tried with official audio adapter as well. The audio clips at startup after few seconds using quick start. I'll try with turning on the camera first, but this seem to be very frustrating. Why tf aren't they fixing this. Their QA is absolute joke.

I think as of the latest firmware released 3/27/24, yes, these bugs are fixed. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rkFKcup8AhM.html

Thanks! I'm going to give it a shot!!!@@WayneRECs

No, i have that problem still after instaling new firmware, and im right now comunicating with dji support for that issue

@@WayneRECs Love this action cam, and use recent firmware, however I hate that everytime I plug in external mic (I used Rode Videomicro) I need to boost Gain more than +8 to get decent sound without modifying at post edit, which resulting a bit crack compared to DJI internal mic. And a bit different than your post in connector, I found a cheap type C DAC converter (mine is showing as AB13X in windows) perform better than Jcally JM6T (w Connexant CX31993), Hollyland Type C to TRS, and Generic Type C to TRS with HD sound. The different between Jcally JM6T and this cheap type C DAC, is sound can be hear more clearly without having to boost gain, +12 in Jcally JM6T is still lower than +8 in cheap DAC. Jcally sound is more subtle, but need to crank gain to the max in the cam and in post to hear decent sound, which overall makes a bit crackling sound. I think it might be related to the ohm specification of the DAC. While for the Hollyland type C to TRS vs Generic Type C to TRS with HD sound, they both pretty similar, barely can hear them eventhough its +12 in the DJI, while the generic one to have a bit higher gain than the Hollyland. So I assumed its DJI internal issue with external mic. Luckily its internal mic is good enough for everything, its just not focus since I think it is an unidirectional mic.
