Hello,

I have a similar problem with hda-intel ALC883 since kernel 2.6.33 (problems are
identical with kernel 2.6.34). There are quick short gaps with the default
options. In turn, bdl_pos_adj=0 results in fast sound as reported here.
position_fix=1 does not fix it.

The card worked fine with previous kernels.

lspci : 

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller
(rev 03)

aplay -l :

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC883 Analog [ALC883 Analog]

  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 6: Si3054 Modem [Si3054 Modem]

dmesg:

[  199.222813] hda-intel: IRQ timing workaround is activated for card #0.
Suggest a bigger bdl_pos_adj.
