Recording with digitech rp355

i pick my recording device in settings but when i hit record nothing hAppeens

Does it record silence or it’s not doing anything? Any error message?

Assuming you’re on Windows, try Try Listen To This Device. If Windows is getting a signal, usually Audacity can record it.

No it doesn’t do a thing slider don’t move nothing it has worked for years sometimes I would have to slide the volume slider from one end to the otherbto make it work but now nothing
