How do I determine what device is already in use.  I'm running FC5 with 
planetccrma kernel.  I removed all spaces from /etc/modprobe.conf, checked:
]# cat /proc/asound/cards
 0 [I82801AAICH    ]: ICH - Intel 82801AA-ICH
                      Intel 82801AA-ICH with AD1881 at 0xd800, irq 10
[root at localhost bin]# cat /proc/asound/devices
  0: [ 0]   : control
  1:        : sequencer
 16: [ 0- 0]: digital audio playback
 24: [ 0- 0]: digital audio capture
 25: [ 0- 1]: digital audio capture
 33:        : timer

I shut down computer, then started computer, have the sound volume 
center thingy on the desktop working, so sound is coming from oss? 
alsa?  But, when I try to start qjackctl, the above message appears.
