All it reflects is that the fix has to go into the kinetic kernel package which will then flow into the kernel-hwe package implicitly. [ Original 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.
