Title:
[9462GAG, Analog Devices AD1981, Green Line Out, Left] Sound is
distorted: clipping is after computer resumes from standby
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
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!
