Hi, I have been able to get around this bug on IBM T60/x1400 running Kubuntu 12.04, by using kwin_gles desktop manager instead of the default one (kwin).
I had problems with sound slowing down and being very choppy when desktop effects were enabled, or when playing full-screen flash videos. I did not notice any problems with wifi. With kwin_gles I have absolutely no sound issues with desktop effects enabled. How to change the window manager see: http://weits.blogspot.cz/2012/02/kwin-gles-as-default-window-manager-in.html I'm not X expert, so please take the following lines as my humble opinion. I belive, that the workaround is caused by the fact, that kwin_gles uses EGL for rendering, while kwin uses GLX. So maybe this bug can be avoided on other distros and window managers by setting them to use EGL instead of GLX. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/879790 Title: Sound doesn't play properly after upgrade from 11.04->11.10, also affects 12.04 Status in X.org XServer - ATI gfx chipset driver: Confirmed Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: After the upgrade from Natty to Oneiric the sound that is played (by any program ex. banshee, VLC, Flash) sound very awkward, like if the whole sound is slightly gargling. My computer: Thinkpad T60 Already tried to solve the problem: The german ubuntuforum has a wiki- page to solve sound problems (http://wiki.ubuntuusers.de/Sound_Problembehebung). Unfortunately, nothing helped - even a reinstalling of the Alsa-Module didn't solve the problem. Hence I think this is a bug. Special: In the thread that I opened in the german forum (http://forum.ubuntuusers.de/topic/nach-upgrade-11-04-auf-11-10 -ueberschlaegt-der-ton/) there was another user that has the same Problem AND he has the same computer as I do. Therefore, I'm not sure if it is a computerspecific problem that may be connected with the chipset of the T60...
