Error 0pening sound device

I am running Windows 10 ver. 1803 and have Sound Blaster ZxR and use the 'What U Hear (Sound Blaster) when clicking on the Record Button. I don’t know what to do. I have never had this problem in my Cool Edit 2000, until I upgraded to the version update to Windows 10. I’m at a loss as to what to do, Using What U Hear is what I use to record music and audio from records, cassettes and the Internet. I can’t use Audacity at all.


So are you saying that you previously used Cool Edit 2000 and Audacity on you computer with Windows Vista, and then updated to Windows 10, and now neither Cool Edit 2000 or Audacity work correctly?

With my recent Windows update I found that as part of the process Windows had kindly turned off the microphone and the stero mix and I had to reenable them in Windows to enable Audacity to see them.
