kubuntu: keyboard volume key always affects the main channel

[lenooh]

Binary package hint: kmix

My keyboard volume key always controls the main channel, which affects only my front speakers (I have a 4.1 setup).

The problem is similar to these:

https://bugs.launchpad.net/ubuntu/+source/gnome-volume-manager/+bug/46007
https://bugs.launchpad.net/ubuntu/+source/control-center/+bug/50388
https://bugs.launchpad.net/ubuntu/+bug/154943
https://bugs.launchpad.net/ubuntu/+source/kdemultimedia/+bug/106926

but I am opening a new bug, because in kubuntu pre-7.10 I could solve it by right clicking on kmix icon and setting PCM as my master channel. In kubuntu 7.10, this does not work anymore. My keyboard volume key always controls the main channel, which affects only my front speakers. It's interesting though, that the mute key IS controlling the PCM channel (or whatever I set as the master channel). So it looks like a bug in kmix in the version of KDE shipped with kubuntu 7.10.

Typo, I meant "master" not "main" channel.

I confirm this behaviour on my Dell Inspiron 9200 - its multimedia keys and the ones on my Logitech G15 keyboard ignore whatever setting you tell KMix is the master channel and always changes the "Master", in my case the stereo channel only - I set it to "PCM" so it should do both, but it doesn't.

It seems that the KDE people are aware of it. There are several bug reports of this:
https://bugs.kde.org/show_bug.cgi?id=134820
https://bugs.kde.org/show_bug.cgi?id=149487
https://bugs.kde.org/show_bug.cgi?id=128224

It seems to be a KMilo issue (the popup that appears when you press volume related keys), that keeps coming back with newer versions of KDE. KMilo does not have an active maintainer, so it may not be fixed. But there are patches in the bug comments.

added upstream bug report

Looks like something related was committed upstream, but if I understand correctly, it wasn't a complete fix. Nonetheless, can you check if this is fixed in KDE 3.5.9 on Hardy?

Bug 154943 also reports this problem, so I am marking this as a duplicate. Please follow up there.
