Public bug reported:
I have an Intel High Definition Audio onboard soundcard, and with the
default Dapper install, the sound I get is scratchy, particularly in the
left speaker.
I also had this problem with Breezy. I fixed it then by downloading the
latest alsa-drivers package at the time (1.0.10) from the ALSA website,
compiling from source, and setting up using alsaconf.
What's funny with Dapper is that the default alsa-drivers package is the exact
same version, yet I got scratchy sound again. To fix it, I installed the
alsa-drivers source package with Synaptic, recompiled with:
# ./configure --with-cards=hda-intel
# make
# make install
then ran:
# sudo /etc/init.d/alsasound stop
# sudo alsaconf
# sudo /etc/init.d/alsasound start
and everything works fine, as for Breezy. Why did it not work with the default
install??? Could it have anything to do with the fact that I upgraded from
Breezy, rather than doing a fresh install?
Anyway, just thought I'd report it, shouldn't be too hard to fix.
I've included some extra info below.
Thanks,
Donald.
