System: AMD A8-7600 (onboard graphics) Radeon R7 KAVERI
Motherboard: Gigabyte AMD FM2+ A68HM-H

HDMI sound out to my home theater via HDMI was working fine for months until a recent system update. I reinstalled Ubuntu 22.04 onto a different drive and HDMI was available. I then allowed the system to fully update and once again the HDMI sound was gone.

As a workaround, I have installed a GeForce GTX 750 Ti and I'm using its HDMI output. The sound is back and HDMI is available once again in the Settings menu.

This is the output with the above workaround installed.

Audio: Device-1: AMD Kaveri HDMI/DP 
Audio driver: snd_hda_intel 
Device-2: AMD FCH 
Azalia driver: snd_hda_intel 
Device-3: NVIDIA GM107 High Definition Audio 
[GeForce 940MX] driver: snd_hda_intel Sound 
Server-1: ALSA v: k5.19.0-35-generic 
running: yes 
Sound Server-2: PipeWire v: 0.3.58 
running: yes

    Can you include the output of the inxi -A command? – Bram Mar 08 '23 at 23:03
