Is it Audacity? M-Audio? or my PC? I can only record one track. Can't Overdub

If anyone can help me I’d be ever so grateful.

I would take a look at these two threads: Error -9985 Opening Recording Device

and

Dubbing not working

Hello, I work on Windows 10 with Audacity 3.1.3 version. I connect microphone to M-track Duo interface to pc to sing. I record the first file and it works fine (and I can hear myself in the headphones while recording). If I try to dub a second file on it, it doesn’t record. I already set M-Audio to “2 channels; 16-bit - 48000Hz” as per supplier instructions and same values in Windows 10 Audio panel. Still not working. So sad I just bought M-track and cannot fix this issue. Thank you for any help…

Please post back what you find.
