I recently bought a Behringer UMC22 for use with a Behringer C-1 microphone. After connecting the unit to my PC everything seemed to be working OK. The mic was receiving phantom power and I was able to record its output on my Windows 10 PC. However, I couldn't help noticing that the PC's headphone monitoring was muted - just as it had been when I used a USB mic. My suspicions were further aroused when I noticed that changing the Output and Direct Monitor controls on the box seemed to make no difference to the sound I was recording. They were confirmed when I removed the audio output lead from the unit and found that audio from the mic could still be recorded. The PC was not receiving (or not acknowledging receipt) of the signal via the soundcard, but was instead taking it from the USB connection, which I had assumed merely to be a power supply for the UMC22. The sound quality on the recordings is OK. There is a little bit of background hiss, but this is far less than I experienced with the old USB mic. So my questions are: 1. How can I persuade the PC to stop using the USB audio and take the audio output from the interface instead? 2. Will doing so result in significantly better audio quality and/or lower background noise?
