Title:
  [22.04] After upgrade to 22.04.2, hdmi audio output is no longer
  detected

Status in linux package in Ubuntu:
  Confirmed

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
