That's what I thought, thanks, will try Pulseaudio (thou I have been 
warned by others).
So am I right in understanding that in a "perfect world", all programs 
will support Pulseaudio (config and mixing) and in-tern it will use ALSA 
to do the lowlevel hardware side?  (thus Pulseaudio will replace all the 
other sound servers and layers out there)
