Title:
Speaker creaks on Dell Latitude E6400
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: alsa-base
First of all, notice that sound used to work well on Jaunty so this is likely
to be a regression (some kind of power saving feature?).
I noticed this problem while testing Karmic for the first time (around alpha
3) and it's still there in alpha 4 now.
From time to time the internal speakers creak no matter if it's muted
or not. Everything works fine, excepts that the speaker creaks
whenever there is no sound played for a couple of seconds (something
around 13 seconds). Its like the sound when you have a speaker plugged
into a power socket and turn on a vacuum cleaner, or anything else
that needs a lot of power for a few seconds.
The creaking is quite loud and really annoying, so I hope this can be
fixed easily.
