audio Q

[Eric S. Johansson]

here's a good one.  On my laptop (dell inspiron 5000) audio works great. 
  Unless I plug in my astronomy webcam (Phillips pcvc690k) which has a 
microphone and activates USB audio module.  Then, xmms and other audio 
applications can't connect the original soundcard.  When the camera is 
unplugged, the system needs to be rebooted and the volume needs to be 
reset before audio works again.

any suggestions for fixes so I can have the camera plugged-in and use 
the laptop sound at the same time?
