Hi!
Affected by this bug, but not exactly bug #1888598.
Config: Asus Extreme Omega integrated HDA Intel PCH as Card 1 + ASUS Nvidia
3090 as Card 2.
Card 0 is an USB webcam and only an audio input.
Problem occurs as described: the audio output changes when the monitor
connected to a DisplayPort output goes to sleep (after locking). No need
for the computer to go through a sleep/wake cycle.
Normal operation is restored by 'pulseaudio -k', then choosing the
correct output using e.g. pavucontrol.
Commands 'pactl list' and 'pacmd list-cards' give different results:
pacmd list-cards:
before: HDMI output is available
ports:
hdmi-output-0: HDMI / DisplayPort (priority 5900, latency
offset 0 usec, available: yes)
properties:

device.product.name = "Acer T272HUL

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
