[SOLVED] HDMI Audio - Can it be muted/disabled?

Hi TheCoolest,

Thanks for your response.

I’ve just double checked everything, I’m definitely getting audio from both the 3.5mm jack and the HDMI with either of the PCM audio devices selected in CE:

alsa:default (aml-augesound analogue), pcm
or
alsa: aml-augesound, pcm

I also reconfirmed that running “amixer sset ‘Audio hdmi-out mute’ on” does correctly suppress HDMI audio, and although persistent through CE restarts, it does not survive a full N2 reboot, and needs to be run again to suppress HDMI audio with either PCM audio device selected.

Many Thanks,

SplittingDistant.
