@Ubuntu Kernel bot : "ISO 9001:2015 specifies requirements for a quality management system when an organization:
a) needs to demonstrate its ability to consistently provide products and services that meet customer and applicable statutory and regulatory requirements, and b) aims to enhance customer satisfaction through the effective application of the system, including processes for improvement of the system and the assurance of conformity to customer and applicable statutory and regulatory requirements. All the requirements of ISO 9001:2015 are generic and are intended to be applicable to any organization, regardless of its type or size, or the products and services it provides." @Ubuntu Kernel bot, take a look. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2009136 Title: No HDMI audio under 5.19.0-35 & -37 (regression from -32) Status in linux package in Ubuntu: Confirmed Status in linux source package in Jammy: Invalid Status in linux source package in Kinetic: Fix Released Bug description: [Impact] For amdgpu/i915, hdmi audio output device has disappeared. [Fix] The latest fix for the non-contiguous memalloc helper changed the allocation method for a non-IOMMU system to use only the fallback allocator. This should have worked, but it caused a problem sometimes when too many non-contiguous pages are allocated that can't be treated by HD-audio controller. As a quirk workaround, go back to the original strategy: use dma_alloc_noncontiguous() at first, and apply the fallback only when it fails, but only for non-IOMMU case [Test Case] 1. boot with kernel applied the patches. 2. check the cards in /proc/asound/cards. Get the hdmi cards. 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xe2320000 irq 137 1 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xe2260000 irq 134 [Where problems could occur] Low, this is just workaround and may have a better solution in the future. [Misc] All patches has been landed on OEM-6.1 and lunar. ~~~~~~ CLARIFICATION: Just to avoid any confusion for those coming to this bug report; the "Jammy: invalid" status above does *not* mean that this bug doesn't affect jammy -- it does, and the kernel team is aware of this. 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. Currently known affected cards: * HD 7700 (comment 8) * R9 290 (comment 21) * RX 550 (LP: #2012141, and comment 27) * RX 570 (mine) * RX 580 (LP: #2009276, and comment 28) * WX 3200 (comment 29) * RX 6600 (LP: #2009542) * RX 6700 (LP: #2009275) [ 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.
