To add to Len's comment above, this could also be the result of Cadence being previously installed and ran on your system, which messes with the user pulseaudio configuration in a way that's incompatible with Ubuntu Studio Controls. As this doesn't seem to be a bug, but user error/support request, I'm closing this bug as invalid.
