Audio device changes issue

I recently started to have issues when changing my audio interface from my native realtek to my TV screen’s audio. When I start a project on either one everyhting seems to be fine. But when I change it, even after changing the ports of my stereo bus I have no sound at all, and I have to recreate all of my instrument tracks in the project for it to work again. I tried restarting the program and even my computer but it doesn’t solve the problem, it actually makes it worse because even when I go back to the device I started the project on, it won’t work either. I don’t know if it’s useful to say but I initially had Cubase 8 LE and never had this issue until I updated to Cubase AI LE 10.5

Hi and welcome,

Can you see the meters on the tracks after the switch? Can you see the meters on the Stereo Out Channel? Did you use Cubase 8 as 32- or 64-bit application?
