HDMI no sound

English Hardware
1

Hi,
I’ve been trying to output the sound via HDMI to a monitor which I’m using. I haven’t managed to get it running, perhaps somebody else has managed to do so.
Built-in Audio: Analog Stereo Duplex - no HDMI available
PulseAudio: Configuration: same, everything else is with (unavailable)
I’ve added some outputs, hope this helps.

Hi and welcome to the Forum :slight_smile:
Is the sof-firmware package installed? You might also want to install pavucontrol and use that to configure.

3

Hi Malcom, thanks for the quick reply.

‘sof-firmware’ is already installed.
No update candidate for ‘sof-firmware-1.6.1-2.9.noarch’. The highest available version i
s already installed.

Regarding pavucontrol, it is installed:

“Built-in Audio: Analog Stereo Duplex - no HDMI available
PulseAudio: Configuration: same, everything else is with (unavailable)”

I’ve checked in Yast Sound and under “Sound Configuration”:
Cannon Lake PCH cAVS

  • The device is not configured

Any tips on this?

Thank you,
BB

Hi
The system BIOS is all up to date, no BIOS settings for sound? Hopefully a Plasma user may offer further advise.

Hi,

BIOS is up to date, same setup works in Windows 10 flawlessly: it shows VG245 on 1050.
Could this be connected to NVIDIA?

Hi
OK so in windows hdmi audio works?

Are you using suse-prime and switching gpu’s?

Your hardware is pretty new (I think with a core-i5-8300H and Intel CoffeeLake) …

I assume the HDMI comes via the Intel hardware, albeit I am not 100% certain.

Could you run some tests, and stop if any one test works.

The test is to run each of these commands, as a regular user, and also with root permissions, to see if anyone of them provides sound:

Trying to push sound through HDMI-0:


aplay -D hw:0,3 -vv /usr/share/sounds/alsa/test.wav

.
and Trying to push sound through HDMI-1:


aplay -D hw:0,7 -vv /usr/share/sounds/alsa/test.wav

.
and Trying to push sound through HDMI-2:


aplay -D hw:0,8 -vv /usr/share/sounds/alsa/test.wav

.
and Trying to push sound through HDMI-3:


aplay -D hw:0,9 -vv /usr/share/sounds/alsa/test.wav

.
and Trying to push sound through HDMI-4:


aplay -D hw:0,10 -vv /usr/share/sounds/alsa/test.wav

I am trying to ascertain if the issue is at the alsa driver level, or at the pulse/pipewire level.
.

Yes:
sudo prime-select get-current
Driver configured: nvidia

In Windows, HDMI sound is being shown as output via NVIDIA.
The hardware is relatively new, a Lenovo Legion Y530.

As for your tests, the slider moves from 0 to 100 but no sound is audible (in the menu of the monitor, HDMI (both ports) sound is enabled and the volume is set to 100):

ok … then for me to understand this new Lenovo, more information is needed. Please run a diagnostic script that provides more information. To do so open a bash shell (ie xterm or konsole) and as a regular user with the PC connected to the Internet send the following command:


/usr/sbin/alsa-info.sh

Select the share/upload option when prompted and let the script run to completion. When it completes, look in the xterm/konsole and it will give you a URL address as to where the content of the diagnostic script output was uploaded. Please past that URL address here on this thread so we can look at it. That may tell us a bit more useful information as to your Lenovo hardware.

OK, thanks, but it moves from 0 to 100 for each of those ? or for only one of those?

What about hw:0,3 ?? If I had to guess, that is the one that IMHO is most likely to yield something useful.

aplay -D hw:0,3 -vv /usr/share/sounds/alsa/test.wav

I don’t know how relevant, but I note there is an arch linux wikifor the Lenovo IdeaPad y530. Is a Lenovo IdeaPad the same as Lenovo Legion? If hardware (for audio) the same, then you could try to add to (or create a new) /etc/modprobe.d/50-sound.conf file, and add the line:

options snd_hda_intel model=lenovo-sky

Reboot and test. If it fails to help, then remove that entry. Do NOT leave it in if it fails to help.

I’ve rerun the tests once again and the bar is loading (pretty much in the same pattern for all tests) to 64% and it lowers then rises for the duration of the tests - no audio output

The script output is disappointing. Your LEAP-15.3 does not have the permissions set up for a dmesg output by a regular user, as I note:


!!ALSA/HDA dmesg
!!--------------

so we can’t get all of the desired technical detail.

I always tune my openSUSE such that a regular user can easily get the dmesg without having to resort to root permissions.

So to save time, can you run that diagnostic script again, this time using ‘sudo’ (and not ‘su’). i.e.


sudo /usr/sbin/alsa-info.sh

and we will see if it gives a dmesg output?
.

13

Hi,
I ran the command under sudo and got the following output - with the ALSA/HDA dmesg filled:

http://alsa-project.org/db/?f=8f033746c3a70a8fc22ecff2db8cb09c6be3690f

Thanks

14

Thanks it appears from the dmesg you have sound drivers loaded correct, albeit its not the dmesg driver loading content i expected to see. However that could just be me not understanding and my having no experience with your hardware. I was expecting to see driver loading info specific to sof (in the dmesg) and less info with realtek codec loading. Again - this could be my misunderstanding.

Honestly, I think this should work. Was this the only one ( hw:0,3) that had bar go up to such a ‘high’ level? or did they all go up to the same?

This looks to me that the issue is at the alsa level … although I suppose its possible the sound at the alsa level is being directed through pulse, and pulse is blocking such (that is wild speculation on my part).

Lets try a test with pulse audio bypassed … ie send this as a regular user, and also as root:


pasuspender -- aplay -D hw:0,3 -vv /usr/share/sounds/alsa/test.wav

Be very exact with the syntax in the above. … In addition to trying hw:0,3, you could also try hw:0,7 and hw:0,8 and hw:0,9 and hw:0,10 … although my speculative guess is hw:0,3 (where I provided the command) is most likely to work.

IMHO you are quite likely in bug reporting territory - which for openSUSE audio is not a bad thing, as a bug report on openSUSE kernel for audio, typically gets the attention of a SuSE-GmbH kernel/sound packager, who also happens to be an alsa-sound driver developer. One of the best persons around for solving such problems.
.

15

Honestly, I think this should work. Was this the only one ( hw:0,3) that had bar go up to such a ‘high’ level? or did they all go up to the same?

I’ve run the syntax as instructed, the bar goes to the same values for all the tests: t[FONT=monospace]hey all went the approx the same, the real value is higher ~64, the goes down to 5x, lower to 4x higher to 5x and then gradually goes to 0; the end result is the same no sound

sudo does not work, see the last output.

I have no further suggestions - other than to consider writing a bug report.

I surfed the internet on your model laptop, and I read of others in different distributions having the same issue, and I could not find one case of someone actually getting the HDMI audio working in GNU/Linux.

I was going to suggest checking the ‘nvidia control’ center and GNU/Linux, but in truth, its been over 10 years since I used nvidia and I can’t recall if there are HDMI audio entries even in such. Further I have never had both intel and nvidia GPU’s on same PC.

I was also going to suggest checking the BIOS to see if HDMI audio disabled there - but you note sound works in MS-Windows, so in that case its unlikely HDMI sound is disabled (unless HDMI sound is disabled in BIOS and Windows ignores BIOS settings - which is highly unlikely IMHO).

As for a bug report, … given its nvidia hardware in this laptop (I assume using a nvidia graphic driver for the HDMI video and audio) it could be that a bug report won’t help … < not sure > .

Best wishes here on this issue, and hopefully either on this thread or in a bug report, someone will know the solution.

One other possibility occurred to me, and that would be to also ask for help on the Lenovo GNU/Linux forum … under “Other Linux distributions” : https://forums.lenovo.com/t5/Other-Linux-Discussions/bd-p/Special_Interest_Linux

Of course given they don’t provide your model Lenovo with openSUSE GNU/Linux they are under no obligation to help you, but I find it a good forum, and often there will be someone willing to help.

I note a thread on T14 AMD no HDMI audio (totally different from your hardware) on that thread … where their solution while not likely relevant to your hardware, was definitely not a solution I would ever have known (its a very long 8-page thread):

In the end, they updated to a 5.15 kernel which solved their problem - but given that their hardware is different, and that a 5.15 kernel could bring in other (graphic driver) issues, I don’t recommend going for such a test. Rather I recommend you could simply post for help on the Lenovo GNU/Linux 'other Linux Distribution" area, and see if someone with the same hardware as you, chimes in with a solution.

Good luck.

Hi,

I will read the entire topic on the Lenovo forum and I will also try to make a thread both there and try my chance with a bug report.
Also, I will wait for the 495 NVIDIA drivers to be stable, as the sound output via HDMI appears to be going via this route.

Here is the output:

That is strange (for me). I expected to see pulse listed as a sound server.

Note previous, the diagnostic script gave:


!!Sound Servers on this system
!!----------------------------

PipeWire:
      Installed - Yes (/usr/bin/pipewire)
      Running - No

Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - Yes

That indicates the pulse audio sound server is running. Yet the inxi command does not show it.

Have you changed any apps/configurations since, so to stop pulse audio from running?
