Description missive 2008-07-09 22:34:08 UTC

Version:           3.0 (using 4.00.85 (KDE 4.0.85 (KDE 4.1 >= 20080703)), compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.24-19-generic

Setting the mute state with KMix does not mute the sound.

I tried muting with alsamixer, and it mutes fine.

I also notice that in the mixer window, the PCM channel does not show a Mute checkbox. All of the other channels have a checkbox to select Mute.

Another oddness is that there are 2 channels labeled "Front", though I'm not sure that is related to this.

While we are talking about KMix muting, Bug #135053 says that middle-clicking the KMix tray icon should mute the sound. I suspect that is not working either, since although the sound is not muting, the Mute option in the tray icon's context menu does show a checkmark when it is selected, but middle-clicking does not affect the state of the Mute selection.

The context menu checkmark desync is fixed in SVN trunk since a couple of days ago. It was a simple UI bug.

Hello,

which control are you talking about? Does this really have a mute state, that can be changed in alsamixer?
Please also post the ouput of "amixer" (or "amixer -c 1" or any other number that corresponds to the affected soundcard).

I am able to get this working the way I want now by selecting "Master" as the Master channel, instead of "PCM".

When I reported this bug, I'm sure that the pcm channel allowed muting in alsamixer, but now it does not. (So the kmix UI matches with the output from alsamixer by not showing a mute checkbox).

It all looks good from where I'm sitting.
