Well! After installing sof-firmware, I am able to get test sound out of the YaST Sound module, but although I have checked the volume settings in Kmixer, still, no sound is produced by e.g. Noatun. Leslie On 2025-03-05 14:20:47 J Leslie Turriff wrote:
You're right, it was not installed. I will reboot in a while and see if it does the trick. In Leap 15.5 this was either unneeded or installed automagically. Sound worked, though I was unaware of this package.

Often it is not installed and that was the problem.

On two machines, I am unable to get sound working. Strangely, the first is my normal working machine, where sound was working on 15.5; the other one is a Lenovo laptop that I'm setting up for my brother. (I'm getting some static from him about how long it's taking to fix this. :-) The problem does not seem to be openSUSE specific; I have tried installing other distros on the laptop, and the sound doesn't work for any of them.)
Here is a possible culprit that I found described online at https://bbs.archlinux.org/viewtopic.php?pid=1446773#p1446773 and some output that might explain my problem:

The solution in the ArchLinux posting above didn't solve my problem, but maybe gets me closer to a fix; the output I get now is:
$ cat ~/.asoundrc defaults.pcm.device 3 rc=0 $ speaker-test -Dplug:front -c2 -l5 -twav -wtest.wav
speaker-test 1.2.10
Playback device is plug:front Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) ALSA lib confmisc.c:1377:(snd_func_refer) Unable to find definition 'cards.0.pcm.front.3:CARD=0' ALSA lib conf.c:5207:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:5730:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2675:(snd_pcm_open_noupdate) Unknown PCM front Playback open error: -2,No such file or directory rc=1
Apparently, 'No such file or directory' is referring to the audio device, not a file?
