[Solved] Kernel 2.6.34 and bad sound

Hello everyone, I've just updated to kernel 2.6.34 and... surprise! Sound is jerkily if I play a video on my machine. If I watch a video, for instance, from YouTube, both video and audio runs faster.
I'm running Arch x86_64 and

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)

is the audio card.

Re: [Solved] Kernel 2.6.34 and bad sound

When you say "play a video on my machine", you mean using a separate video player (outside of the browser), right?

Which video players does this occur in?

Yes indeed, I mean running videos using some player. So, I've been running some tests and that's the result:
Using VLC audio is jerkily, video is good.  Same thing with Dragon Player.
With Mplayer and XBMC audio and video run faster than the normal.
That's all, guys.

Re: [Solved] Kernel 2.6.34 and bad sound

I have that issue, too. No weird dmesg messages, no errors. Tried both w and w/o PulseAudio. Also tried to compile my own 2.6.34 - no difference. (2.6.34 added support for KMS for my machine, but deactivating it had no result too).
ArchLinux x86, KDEmod 4.4.4, using testing repo (problem in kernel only, because i tried to work with my compiled 2.6.34 and with downgrade to core, just now trying to run testing system with my 2.6.33), soundcard:
Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)

Thinking about submitting bug report, just need to read about it and search for already filled one (will be first mine submitted if no one)

If anybody have some ideas how to fix it, please, write! (Preventive "thanks")

Re: [Solved] Kernel 2.6.34 and bad sound

1. Could be a bug in the AMD/ATi chipset. Up until the 890xX, they had plenty of these (and we are not even sure if the 890xX are OK yet).

2. Could also be a BIOS issue.

Some motherboard manufacturers (e.g. ASUS) are notorious for their buggy BIOSes, that affect foremost:

- virtualization extensions
- sound

3. Is this a desktop, or a laptop?

This is Samsung laptop (R20plus, NP-R20FY0C if it helps), three years old, with ATI SB600 chipset and ATI Xpress 1250 onboard VGA card.
It had plenty issues with video (as I said, especially with KMS, but with generic VESA drivers sometimes too), and some problems with correct HDA codec autodetection (until 2.6.33).
Just rebooted into hand-made 2.6.33 under "testing" system, all seems to be OK there.
Also, these glithes are not constant for me, they begin if my system is under load only (not really heavy one, for example, it begin to glitch if I scroll page in Konqueror (my main test for this bug)

The most notorious/buggy of all ATi chipsets.

Literally, there was nothing correct/standard-compliant with it.

Buggy disk controller, non-existent AHCI-compliance, buggy internal clock generator, etc..

Yeah, I've been "lucky" on buggy hardware over past five years...

Finishing my testing for today, try to submit a bug tomorrow. It really seems that problem is only with new 2.6.34 kernel, even if I rebuild it with "good" config from 2.6.33 (with "make oldconfig", of course). Also I think about trying 2.6.35 release candidate next day, will be interesting to see if there are this bug there. If no, then I'll just wait for 2.6.35 release.
Searched in kernel bugzilla too, it was headache and I could skip something, but seems there is no such bug report there.

Re: [Solved] Kernel 2.6.34 and bad sound

I've solved compiling the kernel 2.6.35-rc1 from AUR...

P.S. Is that chipset still that buggy? O.ò
