Interesting … I have immediate access to two PCs, one with openSUSE-10.3(KDE-3.5.7) and one with openSUSE-11.0(KDE-3.5.9) and I don’t have such a pulse audio mixer. Thats the first I’ve seen of it. I suspect it is for openSUSE-11.0 Gnome or KDE4 desktops.
I assume you rebooted like I suggested? (after installing alsa-firmware and changing the model assignment in your /etc/modprobe.d/sound file).
Pulse audio, like KDE4, is IMHO still relatively immature. It could be the lack of maturity of pulse audio in handling the case associated with your audio card is causing this … Hence one approach would be to remove pulse audio! making a note of everything you removed. Then see if your alsa-mixer provides more options.
I did a surf on the alsa web site for stac (yours is a stac9200) and came up with this: Search results - AlsaProject
Changes v1.0.16 v1.0.17 (325,143 bytes)
292: : hda-codec - Add missing descriptions for STAC codec models
which does not seem to relate you your problem. Still, you could always try to update your alsa to 1.0.17 and you can always revert to the older 1.0.16 if 1.0.17 does not work for you. There is guidance here:
Alsa-update - openSUSE
Note there are 6 zypper commands you would need to send. And note you need to restart your PC after updating alsa. I don’t really hold much hope that will work, but I guess it doesn’t hurt to try. Note the 2nd zypper command (that installs alsa, alsa-utils, alsa-firmware, … etc) could have more alsa apps added to match what you currently have installed (ie to update all applicable). If you elect to keep pulse audio, you could also update pulse audio from that repos:
… note those are state of the art, cutting edge rpms, and hence prone to bugs, so pay attention to what you install so you can undo later if need be.
The command “rpm -qa --last” can always help there (to see what was recently installed).
I also note there are some pulse/pulse-audio updates available from the nominal OSS repos (and Main Update) repos that you may wish to try first, before you try anything!
