No HDMI audio with Linux Kernel 7 rc1 or rc2...

No HDMI audio with Linux Kernel 7 rc1 or rc2...

[Gilberto Ferreira]

Hi there.

This is my first post here.
I have compiled both RC1 and RC2 for kernel 7 and after booting with
it, no HDMI sound at all.
This my laptop:

Operating System: Kubuntu 26.04
KDE Plasma Version: 6.6.1
KDE Frameworks Version: 6.23.0
Qt Version: 6.10.2
Kernel Version: 6.19.5 (64-bit)
Graphics Platform: X11
Processors: 12 × AMD Ryzen 5 5625U with Radeon Graphics
Memory: 64 GiB of RAM (47.0 GiB usable)
Graphics Processor: AMD Radeon Graphics
Manufacturer: Positivo Bahia - VAIO
Product Name: VJFE69F11X-B0411H

With kernel 6.19, even the RC's works perfectly fine.
This is how I compiled the kernel:

git clone from Linus github
cd linux
make mrproper
cp /boot/config-$(uname -r) .config
fakeroot make -j$(nproc) deb-pkg


Hope this can be fixed soon.

Best Regards.

Could you give a bit more details?  How it "doesn't work"?
Is the device completely gone?  Or the playback breaks and doesn't
proceed or error?  Or does it output only silence?

You can check /proc/asound/cards and aplay -l output whether you can
see the sound devices at least from both working and broken kernels.

And, if they look different, compare the kernel logs (dmesg ouput)
between them to figure out any relevant differences.

And, beware that HDMI problems are often about the graphics drivers,
not the sound drivers.

Re: No HDMI audio with Linux Kernel 7 rc1 or rc2...

[Gilberto Ferreira]

Hi there...

When I boot with kernel 7 RC1/RC2, I see the Firefox playing and there
is audio activity, but no sound on TV speakers.
When I switch to the onboard card, it works fine.
When I boot with kernel 6.19.5, both cards work fine. In fact, it has
worked since 6.19-RC2.

This the output of the commands:

With kernel 7.0 RC2:

$ cat /proc/asound/cards
0 [Generic        ]: HDA-Intel - HD-Audio Generic
                     HD-Audio Generic at 0xfccc8000 irq 71
1 [Generic_1      ]: HDA-Intel - HD-Audio Generic
                     HD-Audio Generic at 0xfccc0000 irq 72
$ aplay -i
ALSA lib pcm_dmix.c:1000:(snd_pcm_dmix_open) [error.pcm] unable to open slave
aplay: main:850: erro ao abrir áudio: Arquivo ou diretório inexistente

I tried with kernel 6.19.X and got the same output.

This is the onboard sound card:

cat /proc/asound/Generic_1/codec#0  | more
Codec: Conexant CX11970
Address: 0
AFG Function Id: 0x1 (unsol 1)
Vendor Id: 0x14f120d0
Subsystem Id: 0x278212c2
Revision Id: 0x100001

This is the HDMI port:

Codec: ATI R6xx HDMI
Address: 0
AFG Function Id: 0x1 (unsol 0)
Vendor Id: 0x1002aa01
Subsystem Id: 0x00aa0100
Revision Id: 0x100700

I am using KDE Plasma Desktop 6.6.1 with alsa, pulseaudio, pipewire
and wireplumber installed.
But I don't think this is something to do because everything works
fine with the 6.19 series.

Best regards.

Not -i but -l.

But this doesn't matter much now, as the HDMI audio devices seem
enumerated.

So, have you compared kernel logs from both working and non-working
cases?

In anyway, there haven't been so many changes in HD-audio driver
between 6.19 and 7.0 about HDMI audio.  Maybe the only relevant change
would be the commit cb9b6f9d2be6bda1b0117b147df40f982ce06888
    ALSA: hda/intel: Make MSI address limit based on the device DMA limit

Please try to revert this and check whether it brings any difference.

If not, most likely the regression is rather in the graphics driver.
But, it'd be best to do git-bisect to figure out the culprit.

I am so sorry!
Can you tell me how can I do that?

Thank you.

You need to *compare* between two kernel logs.  You can strip the time
prefix, and check which lines appear and which disappear in the new
kernel log.

FWIW, the above is the normal information from HD-audio at parsing the
BIOS info and at binding the interface.

And, have you tested the revert?

Sorry... I am not an expert on this stuff.
I just like to compile the kernel...

How can I do that?
Via journalctl -xe -p3? journalctl -r -b?

>> And, have you tested the revert?
I don't know how to do that.

If you can point me to some doc, it would be nice.

Thanks

You can run "dmesg > dmesg.log" on the running kernel.  And you can
get two outputs.  You can strip the time prefix from there by some
script for easier comparison.

Have you ever built a kernel by yourself?  If yes, it should be just a
git revert of the suggested commit and rebuild / retest.
If not, which (distro) kernel are you using?  Usually you can ask
distro people to build a test kernel.

In general, please be more specific about your system and
configuration.

Re: No HDMI audio with Linux Kernel 7 rc1 or rc2...

[Gilberto Ferreira]

Well... I really don't know what happened.
Probably my fault, as usual.
I do this:
git clone https://github.com/torvalds/linux.git
cd linux
git checkout cb9b6f9d2be6bda1b0117b147df40f982ce06888
make mrproper
cp /boot/config-$(uname -r) .config
fakeroot make -j$(nproc) deb-pkg

But after that, the result was
linux-image-6.19.0-rc1+_6.19.0~rc1-00011-gcb9b6f9d2be6-1_amd64.deb!
I don't get it.

git log shows me this:

commit cb9b6f9d2be6bda1b0117b147df40f982ce06888 (HEAD)
Author: Vivian Wang <wangruikang@iscas.ac.cn>
Date:   Thu Jan 29 09:56:09 2026 +0800

   ALSA: hda/intel: Make MSI address limit based on the device DMA limit

So, basically, I give up!
When this issue gets fixed, I will try kernel 7.0 again.

Sorry to bother.

Re: No HDMI audio with Linux Kernel 7 rc1 or rc2...

[Gilberto Ferreira]

Hi there...

I just installed ArchLinux, because I thought that perhaps
Ubuntu/Debian was the culprit.
So, I went ahead and installed linux-mainline from AUR.
But I get this same result.

Then please try to git bisect.  That's likely the most straightforward
way to figure out the culprit.

Linux kernel 7 RC3 is out and still no HDMI sound.

At best, please try git bisect.  Or if it can't work for you, ask your
distro people who can help.

And, I'm afraid that it's not the sound subsystem but the DRM graphics
driver that actually broke.  In that case, you're reporting to a wrong
list, and further ping wouldn't help.
(And for figuring it out, you'd need the bisection, so going back to
square...)

Re: No HDMI audio with Linux Kernel 7 rc1 or rc2...

I have tried 3 different distros! I don't think this is some distro
related problem.

Hum... In that case, I will address the right list.

No, no, I meant you can ask distro people to build a test kernel, etc,
instead of you.  And, it'd better to ask distros whether you are the
only one in the world who hits the problem.  If it can be reproduced
by others, they can help debugging or bisection, too.  Pinging
repeatedly here on the list doesn't help much, as you can't build and
test a patch, unfortunately.

I am sorry to reach you again, guys, but now I noticed that dmesg shows me this:

amdgpu 0000:04:00.0: [drm] Failed to setup vendor infoframe on
connector HDMI-A-1: -22

This never appears in the 6.19 kernel series.

FWIW, there is another report about broken HDMI auto with amdgpu here:
https://gitlab.freedesktop.org/drm/amd/-/issues/5052

Might or might not be the same issue.

In the end the problem remains the same afaics: you likely need to
bisect this (or hope that someone else that has the same problem does).

Ciao, Thorsten

Hi Thorsten

I think this is exactly the same issue.

Re: No HDMI audio with Linux Kernel 7 rc1 or rc2...

[Gilberto Ferreira]

Hi there...

Some good soul with more skill than myself - obviously - did some
bisec in the kernel 7, and discovered the culprit why some HDMI cards
do not produce any sound.
Here we go:
https://gitlab.freedesktop.org/drm/amd/-/issues/5052

So, this morning I applied this patch to the kernel 7rc5, and it works
without any issues.
