From: Mirix on 18 Jun 2010 05:00 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] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 6: Si3054 Modem [Si3054 Modem] Subdevices: 1/1 Subdevice #0: subdevice #0 dmesg: [ 199.222813] hda-intel: IRQ timing workaround is activated for card #0.

How about 2.6.35-rc3? Another adjustment mechanism was introduced in 2.6.35, so this might work better...

Hi Takashi, Thanks for the advice. However, I have just built 2.6.35-rc3 and it did not help at all.
