Title:
Sound of Rhythm box, Flash and other alsa dependant apps become cracky
and noise from time to time
Status in PulseAudio:
New
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
From time to time sound played by Rhythmbox and Alsa become crappy,
cracky and noisy (for me that it starts to sound like square waves
instead of sound waves or sound like weirdly filtered waves).
Some things that "pull the trigger" was sound events like instant
mesagging events sounds (as in emesene, pidgin and skype).
The problem is more common after a long time of use of the computer,
like 12 hours or so and the more the time the more common, after three
days of continuous usage it happens every three to ten minutes.
It is also common after hibernations, and also, the more you hibernate
the more common the issue is.
If you stop playback for a while, one minute or more, then it becomes
normal again, but if you keep playing sound the issue persist, even
for hours.
To close the application, that is to close or reload a page with flash
(in order to make it reload the flash-player) or close and reopen
rhythmbox make them play the sound right, and 'solves' thew issue
faster than waiting more than a minute.
Anyway it makes it impossible to use the computer to play music in a
reliable way.
