The problem is when I pan right or left the the sound in my headphones goes to the opposite speaker.
For example in the screenshot I have panned hard right. The signal indicates it has panned right but the sound goes to the left speaker.
Headphones are not the problem. I took the left/right stereo test here https://www.audiocheck.net/audiotests_stereo.php and headphones worked fine. Headphones also work normally in Audacity so it seems to be a Cubase problem.
Only happened about a week ago. Anybody else encounter this or know how it can be fixed? Seems like a strange one
