If pulseaudio is indeed crashing for you then that's what we need to
debug. Please:
1. Apply the workaround from bug 994921.
2. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
and tell us the ID of the newly-created bug.
3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where
ID is the contents of the /var/lib/whoopsie/whoopsie-id file on the
machine. Do you find any links to recent problems on the machine? If so
then please send them to us.

Title:
[Lenovo Miix 310, Ubuntu 18.04] Audio no longer working
Status in pulseaudio package in Ubuntu:
Incomplete
Bug description:
I believe this is a pulseaudio regression, as the output of alsa-info
(http://www.alsa-
project.org/db/?f=730ab5b8f0499ef58c0e17f67f8f911ba53a011c) looks fine
as far as I can see.
I'm currently running Ubuntu 18.04, and I believe this is a regression
as audio used to work under 17.10. Since upgrading (which fixed a good
number of other incompatibilities with the machine), I've had no luck
getting audio to work at all.
I'm attaching the output of dmesg, 'aplay -l', 'aplay -L' and
'pulseaudio -vv'.
If I can provide any other information, or if there's anything you'd
like me to try, I'd be happy to help in any way possible.
