Public bug reported:
My laptop failed to suspend overnight and was unresponsive when I opened
it back up. This is on Ubuntu 20.04.2 LTS with kernel 5.6.0-1048-oem and
pulseaudio:amd64/focal-updates 1:13.99.1-1ubuntu3.10 uptodate. In
syslog, I found a stream of suspend attempts with pulseaudio-related
issues repeating in a 40s cycle, so reporting this as a PA issue.

The laptop is frequently connected to an usb dock with an audio output,
and a separate usb microphone with a line out as well, but when the
issue happened it was only plugged in to a charger. It also is often
connected to a bluetooth speaker that may have been in range. While the
system was mostly idle, I may have had (disconnected) mumble, zoom and
discord apps open while the suspend broke and that's about it as far as
audio-using apps go (plus a web browser).

[log pattern repeats]
The laptop is frequently connected to an usb dock with an audio
output, and a separate usb microphone with a line out as well, but
when the issue happened it was only plugged in to a charger. It also
is often connected to a bluetooth speaker that may have been in range.
While the system was mostly idle, I may have had (disconnected)
mumble, zoom and discord apps open while the suspend broke and that's
about it as far as audio-using apps go (plus a web browser).
