Description karl.r.ernst 2011-02-07 22:32:40 UTC

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

Comment 1 karl.r.ernst 2011-02-07 22:38:19 UTC

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.

Comment 5 Christian Esken 2011-08-17 19:42:26 UTC

The Observation from Karl seems to be correct. I can reproduce that. 
Thanks for reprorting. It needs to be fixed.

Comment 6 Christian Esken 2011-12-13 21:14:20 UTC

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).

Comment 11 Christian Esken 2011-12-14 23:31:10 UTC

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.
