I came across what I believe to be this issue: When playing a file in Rhythmbox I would get crackly audio when scrolling in Chromium (was getting crackly audio while using other applications too, but scrolling in Chromium was the most reliable way to reproduce it). None of the solutions for crackly audio I found did anything.
After trawling through plenty of open bug reports I came across this one: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/578342 which suggested it had something to do with the video driver. While I don't have a Radeon card, I was using the Nouveau driver (instead of the proprietary nvidia one). Changing to the nvidia driver fixed the issue for me. I thought I'd mention it here because I haven't found this solution mentioned anywhere else, and it seems related to the issue described here. I don't understand why this work around worked for me, nor do I know how to go about contributing information to see the issue resolved. Hopefully this helps someone. -- 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, also affects 12.04 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
