I have a problem. When I first boot up, all my sound will work fine. The trouble is, I'll inevitably do something CPU intensive like resize a window or click on a link to a flash video, and the sound will cut out. It sounds like a broken record, looping the last millisecond or so over and over again.
When I close everything, kill random processes, and eventually make the loop stop before I go insane, the sound won't come back. The flash plugin will freeze whenever it encounters something that requires sound, Rhythmbox won't play at all, and aplay does the whole broken record thing until I Ctrl-C it.
None of them output anything helpful to the command line.
Audacious will play stuff (!!!), but if I pause it, it goes into the broken record thing. Completing the playing of the track makes it silent, though.
My documentation informs me that in this Toshiba M55-S139 laptop, I have Realtek ALC250 16-bit stereo software sound.
So! I really don't have any clue where to begin to start trying to fix this. I've attached the output of several commands that seemed like they'd be helpful.
Nothing useful shows up in dmesg.
Help?

Sorry to bump, but it's been three weeks and I still have this issue. The firefox Flash Block extension helps cut down on random flash ads with noise triggering it, but it's still there.
Another user, apparently with the same problem (and no forum account?) also emailed me asking if I'd found a solution.
So, yes. Anyone?

Never seen anything like this before, did you follow the arch wiki on how to get sound working? Not sure if this will work but back in the ubuntu days when I was having sound problems I used:
fuser -v /dev/dsp*to track down the process then kill it rather than stabbing around in the dark.

But see, after I kill the offending process, the broken record thing might (or might not) stop, but sound isn't fixed. Next time I try to use Rhythmbox or Totem, they'll crash. If I use Google's Music Manager, more broken record noises.
fuser -v /dev/dsp*
shows no processes using the sound card. I've killed the Gnome volume control widget on the taskbar, but that doesn't seem to have helped. Neither does logging out and in again.

If your using alsa use:
sudo fuser -v /dev/snd/*instead.
I honestly have no idea what could be causing this though you could try restarting the alsa sound daemon
sudo /etc/rc.d/alsa restart.

I dunno either. Running that first command and killing everything using the sound card has no effect, neither does restarting alsa.
I hope this isn't a kernel-level issue.

Thanks to some cool fellows on IRC, it's fixed! (sort of)
The problem is apparently because of some sort of IRQ conflict with the onboard sound card.
adding
irqpoll pci=routeirqto my kernel's boot line in /boot/grub/menu.lst appears to have fixed it. The sound no longer dies.
However, it will skip something fierce when I click a link on a website, scroll, move a window, type too fast...
Any ideas?
