Public bug reported:
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.
