i.MX8QM Android car build doesnt throw audio in headset

Contributor II

Audio is working in non-car build with Android 9 Automotive release from NXP where as it doesnt work with the car build

while looking at the audio_policy_configuration_car.xml bus0_media_out is pointing to cs42888 codec at vendor/nxp-opensource/imx/alsa where i could only find wm8960 codec in the schematics

Only thing happening is the notifications coming in the headset (Alarm Volume and Phone Volume are the only option coming in car build, where as non-car build comes with Media Volume too along with the above options)

Tried to use the working audio_policy_configuration.xml in the car build but board doesnt boot Android. Are we missing something with our understanding? Please suggest

Unfortunately, until the i.MX8QM is completely released, we cannot guarantee if our BSP will work. All the information could be subject to change.

Best regards,
