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:

pulse error

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

Error log file, created with these intructions, on Pastebin.

How do I correct this error?

The solution to this problem was discovered in the course of solving my other problem, with Pulseaudio and Flash.

First I needed to completely purge and reinstall Pulseaudio. One way to do this is to run the command:

sudo apt-get --purge --reinstall install pulseaudio

Then, after I had a clean start, I discovered there was this odd entry in /etc/pulse/client.conf. It had a line that said:

autospawn = now

It seems that now is not a valid option. I have no idea where that option was coming from, as I thought I was starting fresh after reinstalling.

I changed it to yes, and then commented it out as well anyway.

; autospawn = yes

Rebooted, and then I was able open pavucontrol without errors.

The lesson I took from this is that purging an application might not be as complete as one would assume it to be.
