Version: 3.0 (using 4.1.00 (KDE 4.1.0), Debian packages)
OS: Linux (i686) release 2.6.26
After KDE upgrade, my system became mute (using Intel ICH6 sound chip).
Finally, via alsamixer, I was able to unmute and raise the "master" volume and get sound. Note that this is distinct from the "master mono" item and also is not to be confused with the kmix so-called master channel. No corresponding channel appears to be available under kmix.
On my systems (I have two PCs with Intel HDA-based sound chips), the "Master" channel from alsa is called "Front" in kmix (and thus, I have two "Front" channels in kmix). Is that the same with your case?
Version 3.0 Using KDE 4.1.1 (KDE 4.1.0 (4.1 >= 20080722)) (KDEmod) in ArchLinux i686:
I also experience the behaviour described in comment 1. My "Master" channel is named "Front"

Yes, indeed, there is a "front" channel. How should one guess that this is
what used to be called "master"?
I see the logic of being able to assign the "master" channel in kmix, but the
name change is less than obvious. I got stung as the channel was set to 0 (and
muted) by the kmix upgrade.
I also have two "Front" channels in kmix because it renames the Master to Front, while my card has its own Front. I see no reason for renaming any channel, it only causes confusion, e.g. in "Select master channel". It also makes it impossible to assign keyboard shortcuts for the real Front channel as it uses the channel's name as an identifier. And there are really many cards with a Front channel. So, please remove the unnecessary renaming.
The reason for renaming is, because ALSA names the control wrong for many soundcards (The master is no master at all, because it controls only front). This has lead to several bug reports in the past. Now this solution (renaming) also leads to bug reports.
The best way is to roll this back. So by default you get "Master" and if you use a XML profile for your soundcard, you can also receive "Front" if you like.

The renaming from "Master" to "Front" confused too many people. Also it
looks like we only have a hit ratio of about 50%. => Removing the renaming
line from the XML profile.
