i.MX.8QM - Android Automotive 12 Audio Problem

kisstajmi — Tue, 15 Nov 2022 08:14:03 GMT

I Have an i.MX.8QuadMax processor with 88W8997 WIFI&BT module
and I have built a mek_8q_car-userdebug build
from Android Automotive 12.0.0_1.1.0 (Linux 8.10.72 Kernel)

The Problem is:
When I try to play built-in notification sound it works correctly. When I try to play built-in ringtones or I try to play music from a BT connected device or try to make/accept calls there is no any audible sound.

I tried it with multiple headphones & speakers (mono&stereo)

I assume it is an OS bug so how can I fix it?

Hi @kisstajmi

Please refer the 8.2 Audio configuration to route the audio sink:

Thank you but in the 12.0.0.1 version the Android Auto User's Guide is not up-to-date as I see.
There are no config_cs42888.h and wm8960.h files under ${MY_ANDROID}/vendor/nxpopensource/imx/alsa

instead there are json files where the required parameters are set and the bus0_media_out does not working
