I use AudioParameters.suggestOutputChannels() by PdAudio.initAudio(). The suggested output channel is 2 and the result is the phone speaker goes on.
How to turn on the phone earpiece speaker by libpd in Android?
The AudioManager.STREAM_VOICE_CALL returns 0, but then I do PdAudio.initAudio() with 0 as output channel there is no sound at all.
I think i found that there is no straight solution: The libpd contains class AudioWrapper, which creates
track = new AudioTrack(AudioManager.STREAM_MUSIC, sampleRate, channelConfig,
ENCODING, trackSizeBytes, AudioTrack.MODE_STREAM);
so where is no direct way to overwrite AudioManager. STREAM_MUSIC to AudioManager. STREAM_VOICE_CALL .
