OK, that was a stupid question now that I look at it. I just don't understand sound in ubuntu well enough to figure much out.
I reinstalled the entire OS tonight to test the problem since it's annoyingly intermittent. Tonight what caused the problem to appear is raising the dash while in a skype call. Once the 'garbled' sound is triggered, it continues unless I restart. I'm making another pulseaudio log on a clean restart trying to replicate the problem. Unfotunately I don't really know what to look for in the log. More testing shows that even when sound is not completely garbled, scrolling up and down in with a scrollbar makes the sound terrible, clicking on icons, opening files, generally the things one does when running a computer (!) make the sound unusable. I'm attaching a second logfile now, started in a fresh boot and by the end sound was sufficiently terrible to warrant a restart! Please let me know if there is something else I can do to helpfully troubleshoot this bug. ** Attachment added: "second log file (longer) from fresh restart" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/873370/+attachment/2551504/+files/pulseverbose1.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/873370 Title: [Thinkpad 200772U, Analog Devices AD1981] Sound playback distorted, especially when moving cursor with trackpoint, touchpad, or mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/873370/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
