audio problem

Audacity 2.3.2 on Windows 10

Using Presonus AudioBox 22VSL interface, connecting to the computer with a USB cable. Recording acoustic guitar with AKG TPS D3800 microphone plugged into the interface.

I am trying to overdub a second track. I cannot hear the guitar through the headphones when recording the second track.

It all was working well and then suddenly I couldn’t the guitar when recording the second track.

Any ideas are certainly appreciated.

Turn on Overdub in the Transport > Transport Options menu.
