Public bug reported:
This is a report for alsa-base 1.0.20+dfsg-1ubuntu4 on a just-updated
Ubuntu Karmic Beta. (Sorry, I don't know the difference between alsa-
base and alsa-driver, but alsa-driver doesn't have an apt package...)
Upgrading to Karmic Beta has seriously degraded the quality of the sound
coming from my trusty Turtle Beach Santa Cruz sound card.
When the computer is busy, even from something as simple as me clicking
a menu, the sound skips and pops. If I use the volume control applet to
change the volume, the result is *terrible*: it makes "buzzing" noises
where it just repeats whatever sound it was making over and over, and
has about a 50% chance of getting stuck in the buzzing noise or going
back to normal. (If it buzzes, I can try my luck at making it normal
again by moving the volume control again.)
Sometimes, when I start an application, the sound will keep playing but
get incredibly loud and distorted, as if it is being played through a
really bad amp on overdrive.
