No devices in Pulseaudio mixer only "Dummy Output"

[kalpana]

Out of the blue, I lost all audio. This seemed to follow a kernel upgrade, but that could be misleading as I have a couple of updates a day. Nonetheless, everything was working and then suddenly stopped. When I open the Pulseaudio Mixer in the "Configuration" tab there are no devices. I have searched Google and everything I have seen I have tried, and TBH that's made it even worse, as now the mixer is empty! No tabs. Now, small caveate to all this. I seem to have got audio working on some apps, BUT still Pulseaudio is not working. All entries are blank and there is only a "dummy".

All devices are listed and levels are up It gives me this information if any value.

Interestingly, most threads state to try removing the config and restarting, but I get this error:
