UR28M MIC INPUT 1 NOT WORKING

For some reason, I can no longer record using mic input 1. It’s just died, no signal what so ever. It was like this a couple of weeks ago. A simple computer restart fixed the problem but this time that doesn’t work. I’ve updated my drivers but still nothing. Has anyone experienced this before?

I have same problem… rebooted everything, tried a different Mic… and leads… dead as a dodo… The cost of repair just isn’t worth it so just ordered a Focusrite 2i2 Gen 3… It has great reviews and is half the price of the UR28M…
