I have a computer that runs Mythbuntu 12.04. It has an external USB Kenwood Digital Audio device.
When I open up pavucontrol, I get this message:
If I do as the message suggests and run start-pulseaudio-x11, I get this output:
$ start-pulseaudio-x11 Connection failure: Connection refused pa_context_connect() failed: Connection refused
How do I correct this error?
