I believe I'm hitting the same issue, albeit with a Lenovo Miix 310, which previously to upgrading to Bionic had working audio.

Attached is a log of what I get when I attempt to start pulseaudio with "pulseaudio -vv", and the list of devices and PCMs given by "aplay -l" and "aplay -L" respectively.

Status changed to 'Confirmed' because the bug affects multiple users.
