After 10.04 to 10.10 upgrade, sound is full of static

[schwim]

After upgrade, I noticed that audio is full of static. It sounds as if one of the sliders has been pushed too far and it's blowing out the sound. I've tried it across several applications(rhythmbox, browser), and all audio is like this.

I've looked at the audio settings on the dock panel, but nothing seems amiss(and in fact doesn't leave much room for manipulation).

Is there another audio management system I should be using to try to resolve this or might there be something wrong with the upgrade process?

Thanks in advance for your time.

In the General forum, I believe there is a stick post dealing with 10.10 issues, one of them being static. Read that and see if it addresses the problem you're having.
