Hello
I’ve had some Cubase lessons via Skype (sharing screen) and recently when I play Cubase the sounds gets weak or Skype breaks down. My broadband speed is good and my Skype partner says the connection is ‘medium’ quality. Anything I can do about this?
I believe this is caused by a setting in Windows somewhere. Skype does the same thing to videogames for me which I fixed by flipping a switch somewhere in the windows audio options. I’m afraid I can’t remember what it was exactly though 
-edit- here it is:

See if that works for you.
Thank you
