Here is what happens as seen by pulseaudio -vvvv during the monitor
sleep/wake cycle leading to disappearance of the HDMI output:
D: [pulseaudio] alsa-util.c: ELD info empty (for device=3)
D: [pulseaudio] module-alsa-card.c: Jack 'HDMI/DP,pcm=3 Jack' is now unplugged
D: [pulseaudio] device-port.c: Setting port hdmi-output-0 to status no
D: [pulseaudio] core-subscribe.c: Dropped redundant event due to change event.
D: [pulseaudio] module-switch-on-port-available.c: Trying to switch away from
port hdmi-output-0, found no better option
I: [pulseaudio] core.c: default_sink: alsa_output.pci-0000_65_00.1.hdmi-stereo
-> alsa_output.pci-0000_00_1f.3.iec958-stereo
D: [pulseaudio] card.c: Setting card alsa_card.pci-0000_65_00.1 profile
output:hdmi-stereo to availability status no
D: [pulseaudio] core-subscribe.c: Dropped redundant event due to change event.
D: [pulseaudio] module-switch-on-port-available.c: Active profile
output:hdmi-stereo on card alsa_card.pci-0000_65_00.1 became unavailable,
switching to another profile
D: [pulseaudio] sink.c: alsa_output.pci-0000_65_00.1.hdmi-stereo: state:
SUSPENDED -> UNLINKED
D: [pulseaudio] source.c: alsa_output.pci-0000_65_00.1.hdmi-stereo.monitor:
state: SUSPENDED -> UNLINKED
D: [alsa-sink-HDMI 0] alsa-sink.c: Thread shutting down
I: [pulseaudio] sink.c: Freeing sink 1
"alsa_output.pci-0000_65_00.1.hdmi-stereo"
I: [pulseaudio] source.c: Freeing source 2
"alsa_output.pci-0000_65_00.1.hdmi-stereo.monitor"
D: [pulseaudio] card.c: alsa_card.pci-0000_65_00.1: active_profile:
output:hdmi-stereo -> off
D: [pulseaudio] core-subscribe.c: Dropped redundant event due to change event.
D: [pulseaudio] alsa-util.c: ELD info empty (for device=3)
D: [pulseaudio] module-alsa-card.c: Jack 'HDMI/DP,pcm=3 Jack' is now unplugged
D: [pulseaudio] alsa-util.c: ELD info empty (for device=3)
Although slightly redundant, it looks all right.
Part of the problem seems to come from blacklisting HDMI monitors by default
(not switching to them when they are plugged in). But that's the second part of
the problem.
I: [pulseaudio] module-switch-on-connect.c: Refusing to switch to
blacklisted sink alsa_output.pci-0000_65_00.1.hdmi-stereo
The first and major issue is the absence of any event detection when the
DP monitor wakes up.
"pulseaudio -k" restarts the daemon, and probing at startup seems to
find it again.

Title:
PulseAudio automatically switches away from HDMI after display sleep
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
I have an Nvidia based video card that has an HDMI output + a DisplayPort
output.
DisplayPort output audio is listed as "Digital Stereo (HDMI)" and HDMI output
is listed as "Digital Stereo (HDMI 2)".
I prefer to use "Digital Stereo (HDMI 2)".
But after each display sleep (screen lock for example) audio is switched to
built in audio
