Comment 33 for bug 551949

Just for clarification, can you ensure that without the position_fix=1 quirk
the sound is bad? Please make sure to attach "lspci -nv" for all affected
machines for which this quirk resolves the issue.

i am now testing the combination:

2010 x86_64 GNU/Linux

$ tail -n 1 /etc/modprobe.d/alsa-base.conf

options snd-hda-intel position_fix=1
and /etc/default/grub without >any< modifications:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Here i had before: rmi_watchdog=1 additionally

NOW it realy seems to work great (i will test it the next days and
report the results)

In the syslog NOW *nothing* has trouble, *all* the alsa, pulseaudio-errors
reported before are gone! (yes all;))
Now it just says: hda-intel: IRQ timing workaround is activated for card #0.
Suggest a bigger bdl_pos_adj.

I think the watchdog was the reason for the trubble..

let me know if your config includes watchdog
