I just received my new UR22 and every audio recording has a low hum throughout the recording.
Listen to attached sample.
My Focusrite and Audio Kontrol do not have this hum.
All settings, ports, DAW software are identical.
This is attached to a USB 2.0 port , not USB 3.0 port.
Microphone: AKG Perception 220 Professional Microphone (less than a year old) / Works with the other USB audio interfaces with no hum
Computer Specifications: 32 GB Ram, Windows 7 Ultimate, Intel i7-3820QM 2.7 GHZ, 4GB video Ram, 2 SSD hard drives
