Hi all,
While I love my opensuse/kde systems dearly, sound has always been a
hassle here. Sometimes it works fine, sometimes it doesn't work at
all, sometimes it works half.
At the moment, I have a desktop running opensuse 13.1/KDE 4.11.5 on
which youtube sound through Firefox works, but apparently nothing
else. CD-playing, local music files, other-than-youtube movies trough
Firefox, (e.g.
http://vimeo.com/blenderHack/stabilizerdemo) do not work.
In all these cases (including the one where sound is indeed
reproduced!) kmix says there is no sound stream being played.
The sound card is a Xonar STX, which indeed is granted a tab in kmix.
But the menu "Configuration->Sound configuration" shows no hardware at
all, only the PulsAudio server. On the other hand,
"Configuration->Select main channel" says the current mixer is Xonar,
and the channel representing the main volume is the Master of the
Xonar STX.
I tried to remove/re-install the Xonar with Yast (the main
configuration tool of opensuse), but no luck. Testing the card from
within Yast works fine, though.
Frustrating is that is *has* worked a certain time, until some upgrade
(i keep the system in sync with the 13.1 repos for opensuse).
Anyone any idea?
(BTW, I also have a laptop running opensuse Factory, which behaves
just the opposite: everything works, except for Firefox sound... But
that's something for another thread.)

Problem solved.
I came across
"https://forums.opensuse.org/showthread.php/499971-Can-t-configure-sound-card",
where was suggested to throw away /etc/modprobe.d/50-sound.conf, and let
Yast configure the soundcard again. For that problem it didn'nt help (it
appeared to be a hardware problem after all), but in my case it solved
the problem. While the old and new /etc/modprobe.d/50-sound.conf are
exactly the same.
