KMixer and Noatun problems

[Robert Björn]

I have the following sound problems: 
 
1) KMixer's volume control in the taskbar doesn't appear to control my volume, 
but some other slider instead. Can I specify which mixer slider it should 
correspond to so that I can use it like a volume control, like intended? I do 
know which slider in KMixer works for setting the volume. The XMMS volume 
control works properly so that's why I suspect this is KDE related somehow.
 
 2) Sometimes after having played MP3s in XMMS, sound in the rest of KDE stops 
and it goes silent (sounds for system events like opening and closing 
windows, etc). Why? 
 
 3) I get sound in KDE, but Noatun doesn't appear to be able to play MP3s. 
When I launch it from a prompt, I get the following output when I try an MP3 
file. In XMMS it works fine though. 
 
 bash-2.05b$ noatun 
 mcop warning: user defined signal handler found for SIG_PIPE, overriding

 My sound card is a Sound Blaster Audigy. 
 I'd be grateful for any advice.
