I’ve already learned that my Logitech C390e will stream but not record pictures or video on the Monterey OS, so I’m wondering if there isn’t a similar incompatibility here. Once again, the machine is a brand-new Mac Pro 13, M1Chip, Monterey OS. I do believe this is an Apple problem, not Audacity, because it never happened until I switched to Mac a few weeks ago and only just now started using Audacity there. I have attached a screen capture showing that the Device Toolbar reflects two-channel stereo recording, and the correct input/output devices, yet the ambient sound showing in the VU meters is only on the left channel, the waveform of a test recording also shows only in the left channel, and playback is heard only on the left channel. So in the Audacity Device Toobar see, you can choose to record from 1 or 2 channels. When I try to record, Audacity defaults to mono in the left channel only, and I have tried everything I can find in both Audacity and Apple help channels to get both left and right channels running.

Sorry Jademan I’m new here and don’t know how to highlight part of your reply, but here it is: I’m running Audacity 3.1.3 on a brand new Mac Pro with M1 chip, Monterey OS.
