Just got my Nu Audio card from the EVGA store and it seemed to work fine for a few days. One evening I was unable to hear anyone in Discord, despite all other audio working fine. I attempted to restart and was met with the Nu Audio app error "Line in not found !" The app will not open at all after this error appears.
 
I have been unable to open the app at all after this first occurance. Uninstall and reinstall does not fix it. I have followed the directions in and nothing changes. I have tried plugging in a different Line in plug and nothing changes.
