Pi 4C, Audio via HDMI?

I am able to get HDMI video output from Rock Pi 4c okay, but not getting any HDMI audio. Are there any required steps to enable HDMI audio? I was unable to find anything about this via searching and hoping somebody can help.

Are you using Debian image or Armbian?

Sorry for not mentioning that in my original post; Iā€™m using the Debian image provided on the downloads section booted via microSD

apt-get install pulseaudio Pavucontrol
Then look inside
pacmd list-sinks
And select the necessary one with pacmd set-default-sink "SINKNAME"
Also look into

After sleep i will look in details what exactly is wrong
