Topic: Buzzing sound throught speakers
I could use some help with a little but annoying problem: I connected my Roland F140R via USB to Pianoteq on my computer. I connected my computer via a Behringer UCA222 soundcard to the IN-jack of the Roland. I haven't got the budget for a decent set of monitors right now so this seemed a nice solution for now.
Unfortunately I hear a soft but irritating buzzing sound through my speakers. When I disconnect either the USB of the Behringer--piano connection the buzzing stops. When I plug in my headset to the soundcard I hear a perfect sound. So it must be the signal from the soundcard to the piano that gets distorted somehow, or my Roland. Connecting a different soundsource to the speakers of the piano gives a good sound as wel, no buzzing.
Any ideas how I can solve this?
thanks in advance!
