Input and output ports change to highest priority ones when changing screen resolution

• PipeWire version (pipewire --version): 0.3.39
• Distribution and distribution version (PRETTY_NAME from /etc/os-release): Debian GNU/Linux bookworm/sid
• Desktop Environment: KDE 5.23.0
• Kernel version (uname -r): 5.14.0-2-amd64

Description of Problem:

I upgraded Debian from stable (bullseye) to testing (bookworm) which implicitly introduced PipeWire as a replacement to PulseAudio. Running xrandr to change resolutions causes PipeWire to switch from Headphones and Headset Microphone to Speakers and Internal Microphone.

How Reproducible:

Always.

Steps to Reproduce:

1. Switch to Headphones and Headset Microphone if not already done.
2. Change resolution using xrandr e.g., xrandr --output DP-1 --mode 1280x720 --rate 60. [1]
3. Change resolution again using xrandr eg., xrandr --output DP-1 --mode 3840x2160 --rate 60. [2]

Actual Results:

1. Ports change to Speakers and Internal Microphone.
2. Ports are still Speakers and Internal Microphone.

Expected Results:

1. Ports remain the same, Headphones and Headset Microphone.
2. Ports remain the same, Headphones and Headset Microphone.

Additional Info (as attachments):

• pw-dump > pw-dump.log: pw-dump.log
• pw-mon >log 2>&1 before switching resolution: log
• pw-mon >log2 2>&1 before switching resolution: log2

I believe this is related to DP-1, my external monitor, which is probably triggering ports updating thus selecting highest priority ones. eDP-1, the laptop's screen, does not trigger this behavior.

If the above assumption is correct, does that mean PipeWire (PulseAudio-specific) prefers highest priority ports regardless of previous selection and their presence after ports reload/update?
