Comment (by boi):
I'm experiencing the same problem on my machine. I'm running Fedora 9
x86_64, which currently uses PulseAudio 0.9.8. I've experienced this
problem since this summer (not sure exactly when).
The machine is an Athon X2 3800+, with AMD690 chipset ("shared memory" - I
don't play games, so I don't care about blazing graphics performance) and
the ATI SB600. I believe the codec is Realtek ALC883.
{{{
$ uname -r -v -m -o
2.6.26.6-49.fc8 #1 SMP Fri Oct 17 15:33:32 EDT 2008 x86_64 GNU/Linux
$ rpm -q pulseaudio
pulseaudio-0.9.8-5.fc8
$ cat /proc/asound/cards [[BR]]
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xfe020000 irq 16
}}}
The only message from the driver I see at all occurs always right after
starting PulseAudio:
Nov 20 09:11:37 freebie kernel: hda-intel: Invalid position buffer, using
LPIB read method instead.
I've tried using the position_fix parameter, but to no avail. To be
honest, I didn't try much with kernel module parameters. I don't have
issues with my sound not working at all or excessive skipping, which is
what usually pops up when you look for snd-hda-intel parameters.
I can actually somewhat reproduce the problems: when I scroll a page in
Firefox, either by keypresses or mouse, music sometimes skips or even
hangs completely. If I restart PulseAudio by hand, the problem will
usually pop up again, and I'll get the dreaded CPU limit exhausted
messages. Other events seem to trigger this as well (eg. screen
unblanking, switching desktops), but not nearly as reliably.
I've also seen and heard it stop when I wasn't even close to my computer,
so user input is not the only trigger. Nor does my system have to be
really busy when sound goes dead.
Applications don't seem to matter. I have the same issues with Amarok,
vlc, mplayer and Flash.
I hope this is useful. Feel free to contact me if you need more info - it
is really annoying. Last few weeks, I sometimes had to restart the bugger
10 times a day.
