Public bug reported:

After the recent update to the 5.19.35 kernel (installed on 4th March
2023), the HDMI audio (out) of my AMD RX6700 XT doesn't work anymore. I
don't see any devices in Gnome or when listing the devices with `aplay
-a`

In the ACPI error message on startup I see:

kernel: snd_hda_intel 0000:01:00.1: no codecs initialized
kernel: hdaudio hdaudioC1D0: no AFG or MFG node found

When I boot with the old 5.19.0.32 kernel version HDMI audio works
perfectly.
