Same issue here, using completely different audio hardware. This happened after this morning's PA upgrade push in Lucid,

Same problem here. I was just messing around with ardour / jackd and i was not getting any sound. Afterwards realizing that neither output through pulse was possible.

Emu10k1 hardware.
