Comment 0 for bug 417778

I guess this is not a bug directly in xfce4-volumed, but somewhere else, but so far I don't know yet what happens exactly. Every time when my system is idle for some time and the display goes into suspend mode, xfce4-volumed will start to take 100% cpu. Definitely not what I want from an idle system...
From top output with threading enabled I see e.g.

Tasks: 490 total, 4 running, 400 sleeping, 0 stopped, 86 zombie
Cpu(s): 26.1%us, 31.5%sy, 0.0%ni, 42.2%id, 0.2%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 3927536k total, 1927212k used, 2000324k free, 94156k buffers
Swap: 4192924k total, 0k used, 4192924k free, 794384k cached

 5367 bernd 20 0 477m 7692 4508 R 99.6 0.2 53:17.69 xfce4-volumed

(without threading support the shown pid is 5353, so parent parent pid).

strace -p 5367:
poll([{fd=9, events=POLLIN|POLLERR|POLLNVAL}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 2, -1) = 1 ([{fd=9, revents=POLLERR|POLLNVAL}])
poll([{fd=9, events=POLLIN|POLLERR|POLLNVAL}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 2, -1) = 1 ([{fd=9, revents=POLLERR|POLLNVAL}])

Hrm, somehow /dev/snd/controlC1 was deleted, while the filedescriptor was still open. What could be responsible for that?
