I set up the pocket 3 with the mic 2 using the mic2 USB c receiver for best quality. I also do a test video and the sound was ok.

Then I started recording about 40 minutes worth of clips.

I sit down after and every one of these clips bar the test clip has no audio. The mic was on as you can see the red light in the videos.

I also have backup turned on the mic2 transmitter, however there is no audio on here either. It is there for the test clip and then there is just like a 40-minute gap.

I have recorderded a loom screen recording showing the files here and how that 40-minute chuck just has zero audio for no reason.
https://www.loom.com/share/07ecec2b9642426a9f8bbae6e9feab0c

The audio file at 5:02 am is 7 minutes and then nothing.

The video file at 9:04 onwards has no audio. The file at 8:58 does. (note the timezone is 4 hour off on the mic for some reason)

So first of all is there anyway to salvage the audio?

Secondly, why did this happen? It really isn't good enough for a piece of equipment I paid 1000 quid for a few weeks ago.

The mic isn't actually broken either as I set it up again after all this and audio did record.

Please help!

First thing. Always check that the green audio level bar is active. That is your best (and only) indicator that audio is actually being recorded to the camera. It should be active whenever an external mic, or a wireless RX is plugged in and working correctly. If you do not see the bar - stop and work out what the issue is.

With the MIC 2 one thing to check is that the transmitter has not been accidentally muted (though you should get a blinking red vs. solid red light on the TX that shows that).
The other thing to check is that your recording levels were adequate. If too low, then again, you may not see the audio bar.

If the audio was not recorded, then sadly, there no way to recover it. Try opening the files in an audio editor such as 'Audacity' to see if anything at all is there.

One other thing... you are working at very close range and there really is no need to use the RX. It would be fine, and much less hassle, to just use the Bluetooth direct connection. If at long range or in challenging wifi environments, the TX+RX makes sense, but for work within a few metres the BT is fine. There is minimal to no audible difference in 'sound quality', even when listening critically in a studio environment on 1.5K monitor speakers. Certainly nothing your average viewer could possibly detect on Youtube or whatever. Keep it simple. The only sound quality issue you have there is terrible room acoustics. Keep the mic as close as possible to your mouth and you may need to 'de-reverb' it even then. I'd look at hanging some sound blankets (out of shot) to reduce the reverb at source.

Thanks for the reply. I always check the audio bar and record a quick test video. Both were ok. The test video had sound. Then moments later and for the next 40 minutes nothing was recorded in terms of audio.

Even if there was an issue with the receiver it should be on the transmitter but its not.

You mentioned the transmitted might have been muted. I didn't even know this was possible. How would one do this accidently? Is it one of the buttons that mutes it?

I use the TX + RX as its what was advised by DJI if available.

Also from my testing, the sound was actually quite different from Bluetooth vs Tx-Rx. Have you tested the same?

That test clip with the sound was in my office room at new apartment. Haven't got the acoustic panels up yet or carpet down. Sounds like a church

Yes. Many times. The old original firmware on the DJI Mic 2 was very disappointing ('muffled' and 'dull' sounding) and definitely, a  big difference between BT and using the TX-RX. However, the most recent firmware improved things massively and in my opinion, the direct BT connection to the Pocket 3 is now very good. It is still not good with 'phones, but to the Pocket 3 and Action 4/5 - very useable. Make sure you have the latest firmware applied and give it a try.

Even if there was an issue with the receiver it should be on the transmitter but its not.

If you are using the receiver there is a touchscreen button there that mutes everything....it is easy (too easy!) to accidentally mute it when swiping up. You should also see a red outline on the screen of the RX when it is recording correctly. This DOES stay there even if muted, but with a 'speaker' icon crossed out.

Thank you, I think this is what happened somehow. When looking back at the videos the red light on mic seems to be fading (hard to tell on video as I move but does look like the way the light fades and flashes when muted)

Thanks for this input as never new this mute even existed. Every day is a learning day.

As for the mic directly to camera. They are both only a few months old however I am not 100% sure what firmware so will update that and check. Definitely better not to have to use the TX-RX if not needed.

Let firmware update was November, as I recall. I get entirely satisfactory audio direct via BT (as long as the range is not excessive).
