Why am I getting this "Connection to PulseAudio failed" error?
- by Dave M G
I have a computer that runs Mythbuntu 11.10. 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?
Update: Somewhere during the course of doing the suggested tests in the comments, a new audio device has now become visible in my sound settings. I have not attached or made any new device, so this must be the result of of some setting change. The device I use and know about is the Kenwood Audio device. The "GF108" device will play sound through the Kenwood anyway, but not reliably:
