#StackBounty: #sound #kernel #alsa #hdmi No HDMI audio device on intel_snd_hda (Ubuntu 20.04)

Bounty: 100

I have a home server that I want to use as a media server.

But when I connect to a TV, there is no sound.

I’ve tried to update to latest available kernel, and also switch kernel module snd-hda-intel to generic. This fixes issues with no sound device, and now 3.5 jack works, but still no HDMI.

Some extra info:
