Microphone of Huawei Freebuds Pro 4 not used over Bluetooth

Issues

  • Device: OnePlus 9
  • iodéOS Version: 7.6
  • Affected App(s): All

Short Description:

I connected my Huawei Freebuds Pro 4 successfully with my phone via Bluetooth. They work perfectly only the microphone quality was extremely poor, so I considered returning them. Now I found out that the problem is that always the microphone of the phone is used and not of the headset. This affects every application like Signal and audio recorders. This is weird because in SoundTree Recorder, for example, I selected the Freebuds as the recording source, but this did not change anything.

I tested this with another Headset from Jabra with the same result. To me it seems like a general problem.

Does anybody have an idea why this is not working?

New Issue, Regression, or Feature Request?

I tried to dig deeper into this issue and used adb logcat in order to better understand what is happening here. I started logging, then I connected the headset and then I recorded a message in Signal. Afterwards I stopped logging.

Grepping all entries for headset / bluetooth / signal I get the results attached.

I cannot see anything from these log files. Also asking the AI does not really result in a useful answer.

Does anybody have an idea? Would it make sense to raise an issue?

I found another Bluetooth headset from Jabra where the microphone is also not working. The app ”Record Equalizer” is very handy for testing.
