Public bug reported:
Binary package hint: pulseaudio
After a while of desktop usage pulseaudio CPU usage goes to 100%.
The sound still works OK.
running strace -p on pulseaudio gives
ppoll([{fd=4, events=POLLIN}, {fd=9, events=POLLIN}, {fd=29, events=POLLIN},
{fd=28, events=POLLIN}, {fd=26, events=POLLIN}, {fd=7, events=POLLIN}, {fd=20,
events=POLLIN}, {fd=25, events=POLLIN}, {fd=24, events=POLLIN}, {fd=23,
events=POLLIN}, {fd=22, events=POLLIN|POLLERR|POLLHUP}, {fd=22, events=0},
{fd=16, events=POLLIN}, {fd=19, events=POLLIN}, {fd=15,
events=POLLIN|POLLERR|POLLHUP}, {fd=15, events=0}, {fd=14, events=POLLIN},
{fd=13, events=POLLIN}, {fd=6, events=POLLIN}], 19, NULL, NULL, 8) = 1
([{fd=20, revents=POLLERR}])
read(20, 0x7fffc42bf0f0, 72) = -1 ENODEV (No such device)
over and over again.
