iMX8QM Android Automotive OS 10 Phone Call Sound Issue

cbl — Wed, 05 Apr 2023 13:26:42 GMT

Hello,

I am developing on the iMX8QM EVK board with Android Automotive OS version 10_2.4.0.

I updated the "wm896_config.json" file located in the "android_build/device/fsl/common/audio-json" directory as follows.
Thus, I heard the sounds of MUSIC_CONTEXT, NAVIGATION_CONTEXT, VOICE_COMMAND_CONTEXT, CALL_RING_CONTEXT, CALL_CONTEXT over the 3.5mm jack on the board.

{ "driver_name": "wm8960-audio", "bus_name": "bus0_media_out", "supported_out_devices": ["speaker", "wired_headphone", "wired_headset", "bus"], "supported_in_devices": ["builtin_mic","wired_headset"], "support_lpa": 1, "init_ctl": [ {"name": "Left Output Mixer PCM Playback Switch", "type": "int", "val": 1}, {"name": "Right Output Mixer PCM Playback Switch", "type": "int", "val": 1}, {"name": "Playback Volume", "type": "int", "val": 230}, {"name": "Speaker Playback Volume", "type": "int", "val": 120}, {"name": "Headphone Playback Volume", "type": "int", "val": 120} ], "builtin_mic_ctl": [ {"name": "ALC Function", "type": "int", "val": 3}, {"name": "Left Input Mixer Boost Switch", "type": "int", "val": 1}, {"name": "ADC PCM Capture Volume", "type": "int", "val": 230}, {"name": "Capture Volume", "type": "int", "val": 60} ], "out_volume_ctl": [ "Playback Volume" ] }

I connected my phone to the board with bluetooth. I made a call and when the call was made, I could hear the ringtone with my headphones through the jack on the board.

I answered the call but could not hear the conversations through the earpiece and my voice did not go to the caller.

How can I solve this problem?

Can you help me with this?

Best regards,

Efecan

Hello,

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.

Additionally, Android Automotive is supported under Professional Services scheme. You could refer to the following link for additional details:

NXP Professional Services | NXP

Best regards.
