to hear from some other people who were having this problem as well.

Ok, I had some time to compile alsa-lib with debugging and poke at this
a little more. From looking at it, it looks like alsa only opens these
timers when using extra channels - like rear and center. So on 5.1 it's
opening a timer for front, rear and center, while on 4.1 it opens one
for rear

I've done a little more digging and I'm not sure this is a bug in
pulseaudio, or a bug in alsa-lib. After poking around pulseaudio with
gdb for a while, I narrowed down the line where the extra file handles
appear to line 450 in src/modules/alsa/alsa-util.c in the source
retrieved via apt-get
I've got the same issue, with a SoundBlaster Live! 5.1 Dell OEM card. I
also get a file handle leak when using the Analog Surround 5.1 Output
profile - 3 handles leak at a time. When I use the Analog Surround 4.0
Output profile, only two handles leak each time. When using the
(default) Analog
Whew, I just ran into this bug - suddenly I got a message that my file
system was almost full, my CPU was pegged by pulseaudio and rsyslogd,
and a few minutes later my file system was full with many gigs of
/var/log/syslog and /var/log/user.log. About 31 million lines in each
file for pulseaudio:
I can confirm the file handle leak on /dev/snd/timer only happens if I
have the Analog Surround 5.1 Output Profile selected instead of
Analog Stereo Duplex. Three file handles to /dev/snd/timer are left
open each time a sound is played with the 5.1 profile:

Hrm... I wonder if maybe the problem has anything to do with the fact that
the cards have hardware mixing and can be opened multiple times?

I can confirm this bug. I can trigger it with playing quake live ;-),
after that i also have no sound in some programs (totem, vlc, xine,
mplayer), but others work (rythmbox, flashplugin). I have not yet found
a way to fix that without rebooting, restarting pulseaudio doesn't work
strangely.

I'm not sure how to go about doing this, could you provide me with some

pulseaudio -k is getting somewhat old, and it makes my CPU run like
crazy, thus making my fans step up to maximum and also getting to be
very loud.

Yes, it happens with the Ubuntu kernel also:

I haven't the slightest clue what you're asking. I'm using PulseAudio
as it comes with Ubuntu, configured for my number of speakers using the
GNOME Volume control panel.

Right, so you are using glitch-free. Let's see if we can narrow down
whether it's linux or PA at issue, or possibly both. There are
definitely workarounds for either/both.

Hi Marc,
I'm wondering why you removed the security vulnerability flag. This

other software that relies on /var or / not being full.

files is reached. At
It would appear that the best way to trigger it is to play lots of

why, nor can I otherwise explain this highly odd behavior. This means

I suppose I can find out, but if the problem is dependent on the kernel
to be triggered, then this PA bug is a much larger bug than it would
appear to be; PA
