Strange audio behavior in 10.5.2

Hello,

I am experiencing some odd audio behavior in OS 10.5.2.
I am using iTunes connected through the Built-In Line Out to a pair of Altec Lansing speakers with subwoofer.

Recently, I am getting fluctuating volumes with iTunes playback - the volume will get louder for a second and then go back. It doesn't happen regularly, but frequently enough to be annoying. Also, if I pause playback on iTunes, I will hear some noise that resembles rumbling, not really popping or hissing.

It's very strange and I'm not sure what might be causing it.
Any suggestions?

Mac Pro Quad 2.8, Mac OS X (10.5.2)
