Hi

I've been using my UC for years with no issues and today it decided it was no longer working.

I use it on 3 different Macs (all OS Sierra currently) and use it with Nuendo.

today on launch I just got loud white noise through the speakers on launching Nuendo. I have doubled checked software and firmware and all are at the latest version and I am set to use it on a Mac (AP). The set up is no different than it has been up till today.

My total mix however is showing all the channels on the top row as being a full level... Mic 1 through to SPDIF. but I have nothing connected and the faders on them are all down. Any ideas ?
