Everything was working fine … then not. Perhaps a package update caused this??
I have a Dell USB Soundbar and an internal Intel sound device. Both appear in YAST under the Sound entry. The USB sound bar is the default (0) and plays the test sound fine from within YAST.
In Phonon audio setup the usb soundbar and the Intel device appear but are greyed out. The “Dummy output” is the only one that can be selected.
Running /usr/sbin/alsa-info.sh gives me the following entries:
!!Loaded ALSA modules
!!-------------------
snd_usb_audio
snd_hda_intel
!!Soundcards recognised by ALSA
!!-----------------------------
0 [SoundBar ]: USB-Audio - Dell AC511 USB SoundBar

!!Aplay/Arecord output

APLAY

ARECORD

Reading the 1st post and looking at the script output :
Its most interesting that the snd_usb_audio and snd_hda_intel kernel modules (for sound) loaded, but the applications aplay and amixer could not find the sound device. Ergo for other users when they have a problem, this ‘could’ (but not necessary) be a symptom of user permissions.
For my own edification, what did you do to fix the user permissions ? Did you add your user to group audio ?
