No, I do not remember noticing a hang. But I might have moved the Sound preferences volume slider when or before the sound became corrupted. That is the control I used in the last tests.
I have just repeated the test with position_fix=1. The sound distortion I mentioned in the previous test did not occur. But I have heard several jumps (I mean like edit cuts, not seconds of silence). Since you mentioned priority problems, I opened the System Monitor during today's test. During playback, CPU load is abut 65-70% for both cores. However, when the volume control is being moved, it jumps to 100% and stays there until I stop moving it. Same behavior when I opened Applications and moved the mouse in it. I hope I am not going outside of scope---but since I upgraded to 11.10 the Application submenus have been consistently unresponsive for seconds. For example, the Office submenu is displayed instantly, but the selection in it is invisible for a few seconds---moving the mouse does nothing and the CPU load is about 100%, dropping when the selection appears again (pulseaudio not running). However, repeating the test, and keeping moving the mouse inside the submenu for many seconds, the interface become unresponsive and CPU load went to 100% and remained there even long after I exited the area of the submenu---but the sound was not affected. If you like I can attach the logs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/825709 Title: Choppy sound due to excessive rewinding on Atom chipsets To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/825709/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
