Hello,

Is there any way that i can route the audio signals to the audio jack irrespective of a HDMI display connected to the i.MX8M EVK on Android platform?? Or is there any way that i can multiplex the audio output on both hdmi as well as jack?? If so can you please tell me where exactly should i look into to implement these changes.

Regards,

Deexith

Hi Deexith,

In vendor/nxp-opensource/imx/alsa/config_wm8524.h

try to add

.supported_out_devices = AUDIO_DEVICE_OUT_SPEAKER | AUDIO_DEVICE_OUT_AUX_DIGITAL,
