Headset microphone not working in apps, but working for normal calls
Expected Behavior
The microphone of the headset should work normally in all apps, calls and other uses.
Current Behavior
When connecting the headset that came with the phone via the USB dongle, it can be used in normal phone calls without any problems. However, trying to use it with any non-system app (for example a WhatsApp call), sound comes from the headset, but the microphone doesn't work. The apps have permission to use the microphone and work fine when using the built-in microphone instead of the headset. Only when using the headset the microphone doesn't work.
Another user has confirmed that the issue also occurs with the current baseband (MPSS.HI.2.0.c7-00266-0705_2134_5d3eab3e77) and the LOS build from 2021-09-18 in this reddit post: https://www.reddit.com/r/LineageOS/comments/poy1pw/poco_f3_headset_microphone_working_for_calls_but/
Possible Solution
I unfortunately am not well versed in the internal workings of the OS, so I'm unable to give any ideas.
Steps to Reproduce
- Connect headset to phone via USB dongle
- Use an app that needs the microphone, for example a WhatsApp call
- Microphone doesn't work, no sound is being picked up
