By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description TCH 2019-01-16 14:00:11 CST
I have an SB Audigy RX and there is some problem the way KMix handle its channels.

In ALSAMixer i can see the 'Master' channel for both input and output and also i can control them properly.

But in KMix, only the input has it:

http://oscomp.hu/depot/kmix_input_master.png
http://oscomp.hu/depot/kmix_output_master.png

Thus, it's impossible to handle the Master channel from KMix.
And since the Kicker applet "Sound Mixer" uses KMix to handle channels, if i check 'Master' in the channel list, it shows the input, not the output, so i cannot control the Master volume from the tray.

Editing the RC files and disabling/removing capture, showing playback did not helped.

I may be wrong, but as far as I know kmix should display the same channels as alsamixer. Can you post separate screenshots of only the playback channels and output channels?
In my system, master channels are only shown on the output tab. Also please check the full name of the channel in alsamixer: for example on my system I have "master" and "master mono" and when selecting the second one, alsamixed shows the complete name at the top part of the window.

Here is a picture of both playback and record channels in KMix:

The full name of Master in ALSAMixer is "Master".

The command

amixer -q set 'Master' playback 1+

works, so it's "Master".
