Thanks for the advice, Alfredo.
As I write this, some things have progressed. I've autoremoved Pulseaudio from my PC. It seems to have been working backend, and probably creating conflict.
After rebooting, and tweaking input and output in ALSA, I've got Audacity working again. Yeah!
I read somewhere else where someone was scratching their head as to why Ubuntu Studio 12.04 has Pulseaudio. I agree with them. It seems quite unnecessary, especially with ALSA and Jack already available.
