I am writing an application that uses an RME9636 Hammerfall light with the 
ALSA API and every now and then the sound card locks up. It seems unable to 
signal to the computer when there is capture or playback data to be 
transferred and doesn't signal xruns. I am unable to use the card with any 
ALSA applications, aplay etc., until after rebooting the computer. Why might 
this be happening? Could the program be exiting when the card is temporarily 
is a state of being locked? I am using threads, could this have something to 
do with it? And is there any way of resetting the card in software, ie. is 
there any ALSA API function that does this? I would prefer not to reboot the 
computer every time that this happens.

Thanks
Kris Modrak
