iMX8QM Android Automotive OS 10 WM8960 Audio Routing

cbl — Tue, 04 Apr 2023 12:39:22 GMT

Hello,

By modifying the wm8960_config.json file as follows MUSIC_CONTEXT, NAVIGATION_CONTEXT, VOICE_COMMAND_CONTEXT, CALL_RING_CONTEXT, CALL_CONTEXT
I was able to route their sounds to the wm8960 sound card and I could hear these sounds with headphones on the jack on my iMX8QM EVK board.

{ "driver_name": "wm8960-audio", "bus_name": "bus0_media_out", "supported_out_devices": ["speaker", "wired_headphone", "wired_headset", "bus"], "supported_in_devices": ["wired_headset"], "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} ], "headset_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" ] }

However, I want to route ALARM_CONTEXT, NOTIFICATION_CONTEXT, SYSTEM_SOUND_CONTEXT to the wm8960 sound card.

To do this, I updated the elements of the array in the AudioControl.cpp source file. I built my Image.

static int sContextToBusMap[] = { -1, // INVALID 0, // MUSIC_CONTEXT 0, // NAVIGATION_CONTEXT 0, // VOICE_COMMAND_CONTEXT 0, // CALL_RING_CONTEXT 0, // CALL_CONTEXT 0, // ALARM_CONTEXT 0, // NOTIFICATION_CONTEXT 0, // SYSTEM_SOUND_CONTEXT };

However, after Image stood up, it was shut down with the message "Shutting Down".

What steps do I need to follow to route ALARM_CONTEXT, NOTIFICATION_CONTEXT, SYSTEM_SOUND_CONTEXT to my wm8960 sound card?

Could you please help me with this issue?

Best regards,

Efecan
