I've got an older Toshiba Satellite laptop running WinXP that I plan
on using for mobile recording. The interface is an E-mu 0404 USB 2.0.
I'm using Audition 3.0. The 0404 works great on my PC but on the
laptop I get an intermittent buzz/distortion in the
monitors/headphones. The noise is only on the monitors, not on the
recording.

It was suggested that a graphic card might be causing this but
experimenting with IRQ's didnt help. I THINK I might have resolved the
problem by disabling the onboard wireless network card in Device
Manager. (I wasn't using it but it wasn't disabled.) So far so good
but it's a little early to be sure. I was wondering if anyone might
know if I'm on the right track. I know cell phones can cause a problem
but I haven't been able to find much information on an internal
wireless card.

Thanks.

The way things are crammed into a laptop, nothing's impossible :-)
Let's hope you're lucky with the wieless theory. At least it isn't
getting recorded.

The usual problem solved by disabling a wireless network card is
clicking and skipping caused by the wireless network program hunting
up someone to talk to, but any source of EMI can cause buzzing in a
poorly shielded or grounded piece of audio equipment. There's a lot of
that.

Thanks. I know a cell phone "searches" intermittently even when not in
use but I wasn't sure if a mini wireless network card did the same. I
was able to find an updated driver but disabling the card while
recording isn't a problem.
