No sounds mixer controls in Unity

[MadNachos]

Since I installed 13.04 I have not had a working sound mixer in Unity, the mixer exists but it does not see a sound device so the controls don't work. I have been having to use AlsaMixer. Is this a common issue (search didn't find anything)? Can anyone point me in the right direction to fix it?

Thanks much.

Try:
sudo apt-get install --reinstall pulseaudio
sudo reboot

Did You try using pavucontrol to configure PulseAudio...?

Try:
sudo apt-get install --reinstall pulseaudio
sudo reboot

Big hammer approach...
Reboot is not necessary, PA can be restarted nicely... But even reinstall, I think is not necessary... Just tuning...

No dice.

I have never used pavucontrol but I installed it and just ran it and it says 'connection to pulseaudio failed'. So I checked to see if pulse was running and it was not. Running 'pulseaddio' from bash gives me:

W: [pulseaudio] source.c: Default and alternate sample rates are the same.
E: [pulseaudio] module.c: Failed to open module "module-esound-protocol-unix": file not found
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.

So at least I have an idea of where to go next.

ETA: Looks like installing pulseaudio-esound-compat solved the issue. Others have also had this issue as noted here:
