When I listen to this laptop with headphones connected to it directly their is no noise.
When I connect a M-Audio 410 Firewire device to it, and monitor the laptop through headphones connected to the M-410, no hum/noise.
But.
When connecting laptop to mixer and/or amplifier via a stereo mini to RCA cable; the noise is there.
When connecting laptop to M-410 and then connecting M-410's outputs to mixers and/or amplifier the noise is there.
The mixers and amplifier do not hum until the laptop is connected. When connected to any other device there is no noise. And the notebook only produces the buzz when monitored through a second device.
The buzz doesn't seem like a standard ground buzz, as I can here the computer doings its bleeps and creeps.
Any help on what to do, where to start, what the cause is would be much appreciated.
thanks,named
