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.icon_name = "video-display"
    device.product.name = "Acer T272HUL

after:
 ports:
  hdmi-output-0: HDMI / DisplayPort (priority 5900, latency offset 0 usec, available: no)
   properties:
    device.icon_name = "video-display"

pactl list:
