Looking for some advice. We have recently upgraded our pc from a laptop to a MSI I7, 11700 processor gaming computer. I have downloaded the drivers needed, and have the current version of OBS downloaded. We run an Allen and Heath Qu-32 mixer that is connected via USB. Everything is working great except for the sound. I have a constant buzz sound that is only heard when OBS is open, and we get a crackling sound when a mic, or instrument is played. Any suggestions?
