Audio stuttering during AssistantVoiceSession

[harmvddungen]

When I enable the voice assistant in AndroidAuto by saying 'hey google', the music that is currently playing will stop and keep playing its last buffer. This will make the audio very glitchty and stuttering. I tried to find a way to stop this, but I have the feeling this inside the AASDK I am not smart enough to edit.

I did find a workaround but that only solves some bits of the issue:

I edited "AndriodAutoEntity.cpp" and "inputService.cpp" to send a "pause" and "unpause" command to the android auto
And I edited "AndriodAutoEntity.cpp" to mute the music audio channel on the RPI to mute the stuttering. The voice assistent is on a different 16khz channel instead of the 48kHz channel the music uses.

I assume you are using RtAudio? A workaround is to use QtAudio instead. I had an issue with QtAudio where Google Assistant responses were getting cut off, which I resolved by disabling the Speech audio stream in the Android Auto settings within Dash. So far, this seems to work perfectly fine and is much better than RtAudio's buffer stuttering
