I've been trying to Deejay with my Desktop and my Live Value and I have no
trouble at a High School with their system which consists of a Yamaha Mixer
with built-in Amp and two Yamaha speakers but when I deejay at our local bar
I get a big Buzzing sound. Just about the same sound as you get when you
have your computer hooked up to a home system and the RCA PHONO cables
aren't quite in the plug or if you push on the side of the cable end.
Hopefully someone knows what sound I mean.

Anyways I know it's not the cables.  It's not the card.  The mixer volumes
at the bar can be all off including the master and I still get the buzzing
although it gets louder if I bring up the volume.  I have no clue what it is
and I'm just wondering if anyone ever ran into this and found out how to fix
it.

The system at the bar has 2 amps one mixer and 5 speakers on the dancefloor
+ 6 speakers around the table area.  I know it's not the system itself cause
their is no problem with cd's or when I connect my Laptop.  It's weird that
the laptop doesn't cause the same problem but anyways.  It's not the wires
either I don't think because they work with the Laptop. It shouldn't be
anything with the computer or the Live Value Card I have either because it
works at home or on the system at the high school where I deejay.  It's just
something maybe not setup right or something else.

Any help would be appreciated.

Thank You,
