I did some more testing, and no matter which program I try, allegro's 
autodetection hangs until I shut off the other program.
Maybe it's soundcard dependant?

test results

-> start xmms
-> start setup
   setup hangs (black screen), why does setup do an autodetection at startup, even before
   you have pressed the autodetect button?
-> kill xmms
   setup continues
   
---   
->start setup
  ok
->start xmms
-> press setup autodetect button
  autodetection hangs until I kill xmms

---  
->start setup
  ok
->start xmms
-> manually select oss device
  ok
-> test
   hangs until I kill xmms
   
looks a bit problematic to me, I'll investigate more ASAP (it's quite late
now and I really need to go to bed ;-)
