audio sounds "stressed" in ubuntu

[Matt Patterson]

Does it occur more/less when the system is under load or you are moving 
windows around on the screen or playing videos?

I ask because I had the same effect on my system from both a SB Live 5.1 
and a Turtle Beach Santa Cruz but only during load. Turned out it was an 
IRQ conflict with my PCI secondary video card and was also causing 
random system freezes. Out went the video card and away went the freezes 
and the sound problems.

On a different note, make sure you turn off all the recording input 
sources in addition to the changing of all volumes to 75% like recommded 
by the previous email.
