Title:
[Aspire 5551, Realtek ALC272X, Speaker, Internal] fails after a while
Status in “pulseaudio” package in Ubuntu:
Fix Released
Bug description:
This is a really irritating problem that I neither know how to
recreate or how to debug.
After a while of being powered-up the sound on my laptop gets corrupt
for SOME apps and not others. When first started all apps work
together, all noises and sounds work fine.
In my case I mainly use VLC, Rhythmbox and Wine. The fault is not with
Wine as the whole Wine layer can be unloaded and started at any time,
and only occurs randomly after being on for a while. Rhythmbox has
never had this problem.
The sound is severely distorted and unusable. A reboot usually solves
the problem, but sometimes it is still bad and needs to be rebooted
again.
