IMX8MQ: Android: HDMI AUDIO

mps — Tue, 21 Apr 2020 00:24:42 GMT

On my device HDMI video works fine, however audio is always from Audio jack(line out).

Both wm8904-audio and imx-audio-hdmi are detected, however sound/audio for system sounds and video playback is routed via audio jack.

Also attached my audio_policy_configuration.xml file.

Hi MOHIT

first one can try to test audio outputs with linux using for example amixer,

described in Table 7-7. Audio Mixer controls attached Linux Manual

mxc_amix_test\test - imx-test - i.MX Driver Test Application Software

Best regards
