Man, I’m about to rip my hair out. I’m on a Windows 10 machine with a Behringer UMC202HD, and for the life of me Audacity (I’ve got 2.4.2) will only record one input, not both simultaneously. I’m running an Audio-Technica PRO37 mic via an XLR plug into one input; the other input is getting a plain ol’ guitar-amp cord that’s plugged into a Breedlove acoustic guitar. I’ve blown copious time on the Internet trying lots of solutions - no dice. Based on stuff found in this forum, I got all my sample rates equivalent across my output, input, and Audacity (44100) - no dice. Have 2 (stereo) channels selected - no dice. Tried this guy’s (https://www.youtube.com/watch?v=HhbHV-FRk0k) suggestion, to uncheck all those boxes on the Advanced tab - no dice. Shut down and restart - no dice. I know both inputs on the interface are working: on the Sound Settings page, the microphone-test feature shows both inputs working; the interface shows 'em, too, with the signal light lighting up (and the clipping light, too, since I’ve the gains cranked) for both inputs when the respective instrument is played. A curious thing - if I start Audacity with something plugged only into Input 2 and nothing in Input 1, it reads Input 2. Conversely, if I’m plugged into Input 1 but not Input 2, then open Audacity, it’ll read the Input 1 instrument but not the other. If I have both plugged in and start Audacity, it only picks up one. Am I doing something dumb, like just not checking a box or something? I hope so!
Screenshots attached that’ll hopefully help someone out there help my pathetic form right now…and thanks to any of y’all that can throw me a bone here.
