The microphone input from WM8960 Chip is connected to I2S-0.
Tinyalsa was correctly configured for sound playing and then the microphone input was added the same way.
Audio HAL did not print any errors and warnings to logs.
Sound/Music from speaker/headphones is working.
The problem is that no data going from microphone. In the logcat logs I see the ‘open input stream’ actions with stream information. Tinymix correctly changed when board is in capture mode.
Where tinycap tool can be found in Android 9 source code for Edge ?
Does tinyalsa have integration with microphone?
Is there a way to debug microphone issues?
The initial topic was related to audio problem using WM8960 Codec.
