Thanks for the tip. A little too late for me, I'm afraid. I did try different clock sources, but not jiffies, unfortunately (acpi_pm looked promising for a while, but did eventually fail with gargling audio). I've spent countless hours combining kernel and BIOS-options to see if anything helped, but it feels like some kind of fundamental issue that hasn't improved at all since KMS was introduced. Even an external USB audio card pops and clicks, with latency warnings in kernel log, so looks like USB bus suffers as well. Jiffie-clocksource may resolve audio issues (except for the CPU usage), but Radeon-KMS is sluggish on this laptop, and so it's really just annoying to use it. (I got so fed up with this whole thing, that I wiped the laptop completely and installed the oem WindowsXP-cd that came with it. And now everything works amazingly well. Except I don't have Linux on it. Anyways, I only need it as a video playback machinene these days, so.. End of story for me, I will deal no more with this bug.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879790 Title: Sound doesn't play properly after upgrade from 11.04->11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/879790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
