Audio out issue on Imx8qxp

[KDega]

Hi all,

we ported Android Automotive 12.01 on imx8qxp, we are facing issues with Audio.

not able to hear any audio from speakers when we play music files in usb or when we call via BT. 

let me know any configuration changes required.

Dear dega kiran,

For detailed information about audio routing please refer to the Android User's Guide on chapter 8.2 ''Audio configuration''.

In the Android Automotive release, the route is configured as follows: Alarm, notification, and system sounds are played from the audio jack on the CPU board. Other sounds such as music are played from the extended audio board.

Best regards.

Hi @JorgeCas ,

Thank you for reply.

Currently we do not have the extended audio board, can you please let me know how we can reconfigure music app and navigation to audio jack.

we tried the configuration given in Android_Auto_User's_Guide.pdf.

please find modifications which is not working below in configuration file.

<devicePorts>
<devicePort tagName="bus1_system_sound_out" role="sink" type="AUDIO_DEVICE_OUT_BUS"
address="bus0_media_out">
<gains>
<gain name="" mode="AUDIO_GAIN_MODE_JOINT"
minValueMB="-500" maxValueMB="0" defaultValueMB="0" stepValueMB="100"/>
</gains>
</devicePort>
<devicePort tagName="bus0_media_out" role="sink" type="AUDIO_DEVICE_OUT_BUS"
address="bus1_system_sound_out">
<gains>
<gain name="" mode="AUDIO_GAIN_MODE_JOINT"
minValueMB="-500" maxValueMB="0" defaultValueMB="0" stepValueMB="100"/>

Please let me know do we need to do any other modifications in our code for reconfigure music app and navigation to audio jack.
