I just bought a Behringer UMC1820 to record drums and I’m having problems. When it’s set as the primary recording and playback device, I get no signal to the level indicators on audacity and can’t record. If the UMC is the primary input and the computer’s RealTek speakers are the playback device, it shows a signal and can record, but the sound is coming out of the computer speaker with latency. I am stymied. Thanks in advance for any help you can give.
