Sorry I took so long to get back to you.
It turns out Csound is not related to the problem.
In this case I am only using kernel 2.6.33.5-rt23-amd64, alsa lib 1.0.2,
but 2.6.34 does it too.
I bring up firefox. Web pages attempt to play sound. The kernel
begans doing:
[ 2879.766331] allocate_pipes: ch=1 int=2
[ 2879.766332] allocate_pipes: channel already open
[ 2879.766333] allocate_pipes(1) err=-11
[ 2879.766334] pcm_hw_freed
[ 2.821190] pcm_analog_out_open cs=0 oc=2 r=44100
[ 2879.821266] allocate_pipes: ch=1 int=2
[ 2879.821267] allocate_pipes: channel already open
,infinitely. The system is unusable at this point and I have to
Alt-SysRq-k to get back in.
Let me know what other information to provide.
