[Android] Recording of WAV, OPUS and other files fails silently on certain device(s)

[felixmede]

Package version

• 1.2.5
• 1.2.6

Environment

• OS: Android 11
• ONEPLUS A6013

Describe the bug

Recording of WAV, OPUS, aacLc and other files fails silently

To Reproduce

Steps to reproduce the behavior:

1. Create a new Recorder
2. create a new RecordingConfig
3. Start recording with config
4. try to listen to recorder.onAmplitudeChanged
5. stop recording
6. try to listen to recorded file

Expected behavior

creating a useful recording file

Additional context

the amplitude is current:-infinity max: -160
It is working on 1.2.4 without any issues
Other devices we tested work without any issues
No error in console

[llfbandit]

Thanks for the report.
Using wav, opus or aac encoders fails the same way on those devices?
Are they on the same Android version?

[llfbandit]

I made an attempt to fix your issue in compat_effect_issue_393 branch, are you able to test it?
To make it work, you should not use any effect like echo cancel, ...

[felixmede]

I did test it and it is still the same behaviour as before with no audio recorded and current volume being -infinity when recording with aacLc
I used the example project and here is the logs of it

[darajava]

@felixmede @llfbandit I can confirm that this issue is happening with one of my users on Android OnePlus 6T OxygenOS 11.1.1.2

Downgrading to:

  record: 5.1.0
  record_android: 1.2.4

fixes the issue

[felixmede]

It seems to be fixed for me with android_record 1.3.0
