I have encountered this issue today for the first time. A project I was working on suddenly went silent and the Stereo Out channel shows no activity. I don’t have a control room (Elements 10.5). In Audio Connections, the Audio Device shows as Not Connected and you cannot select the usual device. If you delete it and create another one, the same thing happens.
Did anyone find the solution? I get this all the time - it will see my driver (Zoom R16) but wont let me select it. Sometimes a pc restart works but not always.
I couldn’t find a solution. I lost a lot of time because I had to export individual tracks and create a new project to recover it. Really disappointed that there is still no recent patch for Cubase Elements 10.5 users who are dealing with various bugs and issues.
