Default computer audio whine

wrote in message

I have a raidmax case and after having to pull the front
off to fix an intermitting audio out jack, I found the
USB and Audio grounds were tied together on this litle
PCB. The PCB has 2 USB and Audio In and Audio Out jacks.
I used a box cutter to cut and isolate grounds. The
forever whine I've heard is completely gone. The audio
is so clean I can't even hear a hiss.


Good show!

Moral of the story is that the chassis (case) wiring of some computer
hardware was designed by absolute idjiots.
