I’m new to this kind of technology so looking for a bit of help. I recently bought a Behringer U-Phoria UM2 audio interface, downloaded the driver, downloaded Audacity and now trying to connect it all.
When I connect the USB cable from UM2 to PC, the orange LED power light is on. I open Audacity and pull down the Line In menu and select Behringer USB WDM. When I connect my guitar via INST 2 input (and turn INST GAIN 2), the green signal LED comes on when I play. However Audacity does not seem to recognize that my guitar is connected.
When I press the RECORD button on Audacity, I get the message ‘Error Opening Recording Device’ and ‘Error Code -9999 Unanticipated host error’. The error message suggests a bad connection but all seems good. The UM2 is brand new, just out of the box. I am using Windows 10.
Try plugging into the center of the XLR connection (on the left). That’s Line-In which isn’t the same as Instrument, but they are cousins and it may work for you. You may need to turn GAIN-1 all the way up.
Use the UM2 Green/Red lights as guides for volume and do final adjustments in Audacity later. The UM2 red lights may not correspond exactly to Audacity clipping, but they happen first to keep you out of trouble.
One other note. I didn’t apply the drivers. I just plugged it in and started working. The UM2 is not a fancy multi-channel interface with lace doilies and fine wines. It’s just a plain stereo interface that happens to work really well.
One other thing you might try is record in stereo, Split Stereo to Mono with the Audacity tools on the left of the track and delete the dead track. That’s less useful if you want to overdub or play to something else, but that does work.
