Pulseaudio configuration - mathoudebine/openauto GitHub Wiki

AndroidAuto's audio packets are delivered in very small chunks. Due this adjustments of PulseAudio configuration might be needed to avoid audio glitches.

Add/override below lines in /etc/pulse/daemon.conf

resample-method = ffmpeg

In /etc/pulse/default.pa add tsched=0 on the line of 'load-module module-udev-detect'

load-module module-udev-detect tsched=0

After config changes you must restart your pulseaudio instance. You can do it by execution of pulseaudio -k command.
