No HDMI audio on fresh Ubuntu Desktop install

Installed a Fresh, Ubuntu Desktop, img using the Qualcomm launcher and i cant seem to get HDMI audio out.
I’ve followed the Install Documents, I’ve tried enabling/disabling all the audio packages, and
nothing seems to work.

Anyone have some insight?

May I ask if you have switched to the HDMI audio channel

HDMI OUT playback in the document

ive done everything in that documentation. i ended up downloading and flashing the Official Ubuntu img and not updating it. Seems like something in the update breaks the audio.

What brand is your monitor and does it support audio input/output?

it is an Acer. it does support audio input/output. the audio output from the Rubik Pi is currently working as long as i don’t update it.
