Looking through the growing list of duplicates, everyone has an AMD GPU so this is almost certainly an issue in that driver. The list of cards affected so far:
* RX570 (mine) * RX6700 XT (from LP: #2009275) * RX580 (from LP: #2009276) * RX6600 (from LP: #2009542) I'm happy to post any additional logs / traces that would help debug this and/or test patched kernels (worth looking at the duplicates for additional logs too). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.19 in Ubuntu. https://bugs.launchpad.net/bugs/2009136 Title: No HDMI audio under 5.19.0-35 (regression from -32) Status in linux-signed-hwe-5.19 package in Ubuntu: Confirmed 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.
