Reaper Hum Loop?
Hi, I'm using Reaper on a HP laptop connected via USB to a Focusrite 4i2 (second generation). All was well until I had a problem with the hard drive and had to reinstall Reaper and the Focusrite drivers. I can connect the laptop to the Focusrite and then to the PA system, but as soon as I start Reaper, I get a hum and a kind of swirling phasing sound through the PA, close Reaper and the sound goes away, If I disconnect the laptop from the power supply, even with Reaper running, the sound also goes away. Has anybody come across this before?, thanks
