All of the sudden, when I join a Zoom with my XLR interface set as the audio input, people only hear me out of their left audio channel. This didn't used to happen, but either with a recent Zoom update, or with macOS Catalina, something changed. Any ideas?
Good to know it wasn't just me! For what its worth, I solved the issue by using a tool called Loopback to create a virtual audio device that mapped both L&R channel to the mic's L input. Its not cheap, but a useful tool - rogueamoeba.com/loopback/
@cleverdevil could your mic input be setup as a stereo input? Does your xlr box have a “pan” or “balance” setting? Also, check audio midi settings (search for “midi” in spotlight) on your Mac. After that, ¯_(ツ)_/¯
