Version: unspecified (using KDE 4.6.0) OS: Linux Previously before the upgrade, everything worked fine. But after update to 4.6, some audio channels went missing in KMix. They can't be found in the channel configuration dialog either, but they still show up in alsamixer. Some channels are e.g. "Sigmatel 4-Speaker Stereo" or "SB Live Analog/Digital Output Jack" Soundcard: Creative SB Live! 5.1 Soundsystem: alsa (as in no pulseaudio) PS.: I cannot select 3.8 as application version, thats why I left it unspecified Reproducible: Always
Actually, it seems like all the options in alsamixer which are only on/off toggleable and don't have a volume slider have disappeared, while those with a volume slider (even if they have a on/off option) are still there.

A nice ressource http://pulseaudio.org/wiki/KDE
The Observation from Karl seems to be correct. I can reproduce that. Thanks for reprorting. It needs to be fixed.
I have an idea what is wrong but need some information: - Which sound backend is used. Please copy the output from KMix menu => Help => Hardware information - The ouput of "amixer" (or "amixer -c 1" or any other number that corresponds to the affected soundcard).

Created attachment 66759 [details] amixer output of the affected soundcard
Help => Hardware information says: supported driver: ALSA + OSS used driver: ALSA will try the patch probably on the weekend
I just noted that my patch is not sufficient, but I found a way to reproduce it. See the duplicate bug 257953. I'll mark this bug as duplicate. *** This bug has been marked as a duplicate of bug 257953 ***
