Just looking for some help with my UR44. Seems that all of my inputs are picking up some sort of sound without any input while gain knobs are all the way down . In Cubase 8.5 it shows low audio activity signal and when I remove the default stereo input the audio activity goes away. Ive fastened the ferrite core to the USB Cable near the USB 2.0 terminal. Ive downloaded and installed both latest firmware and drivers. I had a Presonus Firestudio before this with zero issues. Not sure if I should start packing up the UR44 and return it or keep troubleshooting. If anyone has experienced anything similar or resolved the issue I could use some help! Thanks!
