Bug Description
This is a report for alsa-base 1.0.20+
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.

A little more Googling found me Bug #428619 in pulseaudio, which is describing the same problem.
This bug claims to be fixed, but I have the version of pulseaudio in which the fix was supposedly released.
