Jamie, I would say you're now hitting a different issue now, and it doesn't look like a kernel issue. Maybe it's worth opening a different bug report.
Anyway, it looks like you all agree that the lp1013183v2 seems to fix the original issue reported in this bug. Could you please also check whether this issue is fixed upstreams? You can get the latest kernel build (v3.5-rc4) here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc4-quantal/ (Btw, sorry for taking so long replying) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1013183 Title: Sound playback stopped working in 3.2.0-25 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1013183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
