@bpl indeed -- I asked Timo if the targeting should be adjusted in
comment 9 as I wasn't sure if the kernel team wanted to track this
separately over in the hwe package, but given this bug was moved from
that package this one I may as well just add jammy to the affected set.
** Also affects: linux (Ubuntu Jammy)

Title:
No HDMI audio under 5.19.0-35 (regression from -32)
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Jammy:
Confirmed
Status in linux source package in Kinetic:
In Progress
Bug description:
After upgrading my Ubuntu jammy (22.04) desktop to the -35 release of
the kernel, I found my HDMI audio output device had disappeared.
Reverting to the -32 release caused it to appear again (hence why I'm
filing the bug against the kernel rather than pulseaudio). I'm
attaching the dmesg output from immediately after booting each kernel,
but after a bit of trimming and diffing I *think* the following lines
are the salient ones:
input: HDA ATI HDMI HDMI/DP,pcm=3 as
/devices/pci0000:00/0000:00:03.1/0000:2b:00.1/sound/card0/input12
input: HDA ATI HDMI HDMI/DP,pcm=7 as
/devices/pci0000:00/0000:00:03.1/0000:2b:00.1/sound/card0/input13
input: HDA ATI HDMI HDMI/DP,pcm=8 as
/devices/pci0000:00/0000:00:03.1/0000:2b:00.1/sound/card0/input14
input: HDA ATI HDMI HDMI/DP,pcm=9 as
/devices/pci0000:00/0000:00:03.1/0000:2b:00.1/sound/card0/input15
input: HDA ATI HDMI HDMI/DP,pcm=10 as
/devices/pci0000:00/0000:00:03.1/0000:2b:00.1/sound/card0/input16
input: HDA ATI HDMI HDMI/DP,pcm=11 as
/devices/pci0000:00/0000:00:03.1/0000:2b:00.1/sound/card0/input17
snd_hda_intel 0000:2b:00.1: bound 0000:2b:00.0 (ops
amdgpu_dm_audio_component_bind_ops [amdgpu])
These lines appear in the dmesg of the -32 kernel, but not in the -35
kernel's log. Meanwhile, the following lines appear in the -35
kernel's log but not in the -32:
hdaudio hdaudioC0D0: no AFG or MFG node found
snd_hda_intel 0000:2b:00.1: no codecs initialized
I'll also attach the output of "pactl list" under each kernel (this
shows the HDMI audio sink showing up under -32, but not -35) just in
case that helps shed any light on things.
