Describe the bug Some Android devices record as expected but when playing this record file, no sound is heard. If I try to play this record file on other devices, there is no sound either.

Additional context**

This problem is faced in a BQ X2. Moto G9 works fine. No problem found in iOS.

Of course, done! And trying to send a Paypal tip for a super coffee (not sure if it worked, I’ll review again in hours 😄).

Thank you very much!

Well, I realized where is the problem (in my application). Your comment about the mute state was the trick.

My app can do VoIP calls. If I mute the microphone when calling, the record I do later is blank.

You are completely right with that:

The minimum I will do, will be to add this instruction to Mute OFF.

My fault 😓
