** Description changed: After turning computer on and before sending it to standby sound is played normally but after resuming from standby sound is distorted. This affects both programs that use gstreamer (Banshee) and at least one that doesn't (Audacious). Have tried the three suggestions on https://wiki.ubuntu.com/Audio/PositionReporting but none is able to fix the problem. This problem seems to get worse under high CPU load. Curiously, if a music is playing and I press reboot, in the time between clicking 'Reboot' and the actual reboot, sound is played normally, meaning, the clipping and distortions disappear during these 2-3 secs that it takes ubuntu to close all processes and restart the computer. + [EDIT] It also affects Ubuntu 12.04 Beta 1! + ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: alsa-base 1.0.24+dfsg-0ubuntu2 ProcVersionSignature: Ubuntu 3.0.0-16.28-generic 3.0.17 Uname: Linux 3.0.0-16-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
