Sound setup in OpenSuSE 15.6

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: # ls -l /dev/snd total 0 drwxr-xr-x 2 root root 80 2024-11-18 17:36:20 by-path crw-rw----+ 1 root audio 116, 6 2024-11-18 17:36:20 controlC0 crw-rw----+ 1 root audio 116, 10 2024-11-18 17:36:20 controlC1 crw-rw----+ 1 root audio 116, 5 2024-11-18 17:36:20 hwC0D0 crw-rw----+ 1 root audio 116, 9 2024-11-18 17:36:20 hwC1D0 crw-rw----+ 1 root audio 116, 2 2024-11-18 17:38:19 pcmC0D3p crw-rw----+ 1 root audio 116, 3 2024-11-18 17:38:19 pcmC0D7p crw-rw----+ 1 root audio 116, 4 2024-11-18 17:38:19 pcmC0D8p crw-rw----+ 1 root audio 116, 8 2024-11-18 17:38:19 pcmC1D0c crw-rw----+ 1 root audio 116, 7 2024-11-21 16:30:17 pcmC1D0p crw-rw----+ 1 root audio 116, 1 2024-11-18 17:38:19 seq crw-rw----+ 1 root audio 116, 33 2024-11-18 17:36:19 timer 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?
