Title:
[Karmic] HDA Intel: sound messed up after a while (cracks, rings, no
other audio possible)
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
Since about 3 days ago, after a certain period of time of using the
audio output (whatever the program, either totem, vlc, flash, and
whether with a single user connected since boot or with a second user
session opened) the audio changes abruptly to a mix of cracks and
rings (listen to the attached audio output). Nothing seems to correct
the problem, even though it seems possible to get the audio back to
normal by closing all audio applications for a little while (less than
30 seconds AFAICT), including Firefox when there's a flash video on
pause, and trying again (if a second user is connected, same story,
even this user audio apps need to be shut down).
The computer has an ICH10 Intel controller (GB EP-45 DS4). The
computer is also affected by bug #433654, but the problem reported
here wasn't there before (using Karmic since Alpha 4) and appears even
if only one user is connected after boot.
I've left Totem open with the problem while reporting the bug with
ubuntu-bug. Computer has all updates, and was just booted 20 min ago,
with Totem playing audio for about the same time before the problem
occurred, and a single user logged in.
