[X4U] USB speaker static

[Steven Rogers]

I've got a set of Monsoon iM-700 flat panel USB speakers, and they seem 
to have a lot of static - wondering if this is a problem with my 
speakers/system or if its common to all USB speakers. The symptom is 
just a fairly loud static background behind any audio. Seems to be 
about the same across all applications - iTunes, iMovie, etc. The 
static is always a constant proportion of the sound when the volume is 
adjusted. In other words, if you turn the volume up and down, the 
volume of the static goes up and down along with the audio (works the 
same with application, system, or speaker "puck" audio control).

Its always been there but it seems worse with later system updates. 
Hard to tell if its getting worse, or if it just annoys me more. I'd 
consider switch to a different brand of speaker, but not if its a 
system issue. Any comments or experiences welcome.

Thanks,
Steve
