Without mentioned DEBUG options everything seems to be ok except when
skype and xmms are running together. Then this appears occasionaly:

  2nd 0xc245a200 pcm0:record:0 (pcm record channel) @

Maybe this has something to do with problem someone mentioned with skype
and kde? Btw. this has happened while I was running skype+xmms under mwm.
