Title:
[22.04] After upgrade to 22.04.2, hdmi audio output is no longer
detected
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi, since upgrade to Ubuntu 22.04.2, I have no longer HDMI audio input being
detected.
It doesn't show as an option in Sound settings and thus doesn't output audio
to a monitor attached via HDMI.
I noticed the following logs in dmesg:
[ 5.466172] snd_hda_intel 0000:08:00.1: Handle vga_switcheroo audio client
[ 5.466174] snd_hda_intel 0000:08:00.1: Force to non-snoop mode
[ 5.466399] snd_hda_intel 0000:0a:00.4: enabling device (0000 -> 0002)
[ 5.468656] hdaudio hdaudioC0D0: no AFG or MFG node found
[ 5.468672] snd_hda_intel 0000:08:00.1: no codecs initialized
