I tried to change my speaker setup and every time I click "test" I get this error message on Windows 7 SP1. I tried running "sndvol" to view the applications list but the list is empty.
Since I tried to test the new speaker setup, I'm now left without sound for all applications and can't get sound even if I switch back.
I have not updated my sound drivers so I don't know what could have changed.
What could be causing this?
