weird constant hissing sound coming from one speaker

As soon as the peripherals started, an error popped up on screen
indicating an error and the window also had a backtrace tab.
Since that time there is a constant hissing noise coming from the left

I am running 2.6.7 kernel and the sound card(as lspci shows) is:

info (I am not sure where to start). My apologies. But if somebody could
get me started in the right directoin, I can investigate further what
could be wrong.
