Description Nathan Wolf 2023-08-10 16:34:07 UTC

There is no sound output over HDMI. This includes sound over USB-C devices as well.

When I conduct a speaker test on an available HDMI device here are the results:

speaker-test 1.2.9

Playback device is hdmi:CARD=PCH,DEV=0

I am hoping I can help provide information to work out the sound issue. Not sure if it is an openSUSE issue, a Kernel issue, lack of support for the 13th Gen Intel or maybe something else. I am not interested in using any other distro so I would rather just do what I can to help work through the problem.

Comment 1 Takashi Iwai 2023-08-14 13:46:25 UTC

Could you give the dmesg output after a fresh boot?

It seems that proper HD-audio codec modules aren't loaded at the initialization of HD-audio bus.  Did you put snd-hda-intel driver (wrongly) into initrd?
Please give the output of lsinitrd, too.

Comment 4 Nathan Wolf 2023-08-23 15:12:55 UTC

Here is the info.

Comment 5 Takashi Iwai 2023-08-24 15:38:56 UTC

And the HDMI audio really doesn't work with that state?  The dmesg output looks pretty different from what's included in the original alsa-info.sh output.
Please double-check.

Comment 6 Nathan Wolf 2023-08-25 02:06:27 UTC

I just checked it again and there is no HDMI audio output. There is video but no Audio.

Comment 7 Takashi Iwai 2023-08-25 07:27:41 UTC

OK, then please give alsa-info.sh output again with the non-working state, but  *during playback of HDMI*.
Run the script with --no-upload option and attach the output to Bugzilla.

Also, give the dmesg output, and the contents of /proc/asound/card*/eld#* files at that point, too.

alsa info run locally with an HDMI device plugged in

I have a portable USBC monitor that works with my HP EliteBook providing HDMI out but not with the Framework. This is a known working hardware configuration so hopefully the alsa-info provides some clue as to where the breakdown is occurring.

Could you give alsa-info.sh output from HP EliteBook connected with that monitor, too?  I'd like to compare with the working case.

Also, could you check /proc/asound/card/*/eld#* files, too?  I guess the Framework doesn't show the monitor connected there, while HP should show the proper contents with ELD.

If so, it's likely a problem in the graphics driver side, and if the problem persists with 6.5 kernel (found in OBS Kernel:HEAD repo), we should report it to the upstream.

Comment 11 Nathan Wolf 2023-08-26 20:25:56 UTC

I am a bit confused on what you want me to do with this:

/proc/asound/card/*/eld#*

"card" is a file and the output for each is this:

Framework:
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0x605d1c0000 irq 184

EliteBook:
 0 [sofhdadsp      ]: sof-hda-dsp - sof-hda-dsp
                      HP-HPEliteBook840G7NotebookPC--8723

But that doesn't seem like what it is that you want.

You did put one too many slash.  It's /proc/asound/card*/eld#* files.
Something like
  /proc/asound/card0/eld#2.0

Comment 13 Nathan Wolf 2023-08-27 14:40:46 UTC

I think I got it but I ran this when I was away from my desk so the monitor is not attached. I can run this again with attached if this is not satisfactory.

Comment 14 Takashi Iwai 2023-08-27 17:16:45 UTC

Yes, please check with the monitor connected.  The only point is whether the graphics / audio drivers could detect the HDMI audio and expose via EDID/ELD.

If no connection is seen in eld#* files, it means either the graphics driver couldn't detect the audio capability, failed to advertise to the audio driver or the audio driver missed by some reason.

(In reply to Nathan Wolf from comment #15)

And the problem still persists?
I'm asking because now the driver looks successfully detecting the monitor:

Comment 17 Nathan Wolf 2023-09-18 02:36:09 UTC

The problem still persists. I am testing it now with no HDMI audio devices detected.

Comment 18 Takashi Iwai 2023-09-18 06:09:15 UTC

Then please give alsa-info.sh output at the latest state.

Comment 19 Takashi Iwai 2023-09-18 07:06:01 UTC

... and check the /proc/asound/card*/eld* files again and confirm that the monitor is detected there.  If eld* file shows the monitor present while alsa-info.sh output shows no corresponding ELD control element with the monitor present, it must be the problem.

Just as an addition. I thought I would add this:

I see that HDMI has the monitor identified.

Comment 23 Takashi Iwai 2023-09-19 06:42:45 UTC

OK, interesting.  At this state, what happens if you run like
  aplay -Dhdmi:0 -/usr/share/sounds/alsa/test.wav
?

Doesn't this produce any sound over the monitor?

Comment 24 Nathan Wolf 2023-09-19 15:25:09 UTC

That worked!

aplay -Dhdmi:0 /usr/share/sounds/alsa/test.wav

The sound was clear, crisp and had no "glitching" whatsoever.

Comment 25 Takashi Iwai 2023-09-20 07:54:24 UTC

It's a good news, finally.

Then the problem seems to be rather in the user-space sound service.
Are you using pipewire?  Or PulseAudio?

Comment 26 Nathan Wolf 2023-09-20 13:35:21 UTC

I am running the default Pipewire setup from Tumbleweed. This machine was installed fresh in June 2023.

Comment 27 Takashi Iwai 2023-09-20 14:14:56 UTC

OK.  And when you run pavucontrol, can you choose the display audio as the output?  Or does it still show as unplugged?

Comment 28 Nathan Wolf 2023-09-20 14:24:20 UTC

The HDMI Display audio doesn't show up as an option. Under the "Output Devices" Tab, I only have my "Built-in Audio Analog Stereo with Speakers and Headphones (unplugged)

Under the "Configuration" Tab, I can select it as an output. This is newly working like this and is not how the HP EliteBook presents the output. Maybe this is better? I don't know. What do you think? Is the problem now solved?

Comment 29 Takashi Iwai 2023-09-20 14:37:46 UTC

Ah, this can be the difference of the sound driver, and how it's represented on user-space.  I guess UCM profile is applied to SOF driver and those appear as individual outputs.  OTOH, with HDA-Intel, it's a single entity and appears as different profiles.

Comment 30 Nathan Wolf 2023-09-20 14:43:28 UTC

Is there any way to get the UCM profiles applied to the HDA-Intel drivers or is this not as simple as selecting and applying a profile to the HDA-Intel drivers?

No regressions as of openSUSE Tumbleweed 20230922. HDMI audio continues to operate normally. The profile selection for HDA-Intel Audio doesn't allow for the same flexibility as the sof-hda-dsp but it does work well and I consider this to be resolved.
