OK, I went back to the xenial 108 kernel again and the issue came back..
I tested further and found that only certain applications are exhibiting
this. For example, it's happening in VLC and Chrome, but not in audio
played by FF.
Going to close this as it looks like it's probably not a kernel thing.

Title:
Audio clips after kernel update
Status in linux package in Ubuntu:
Invalid
Bug description:
After updating to 4.4.0-112 on xenial, getting constant buffer
underruns in pulseaudio, causing frequent clips where the audio cuts
out for a fraction of a second.
Booting back into 4.4.0-108 consistently resolves this issue.
This issue is reproducible on 4 different audio cards of varying
manufacturers, including Intel, C-Media, and Turtle Beach.
