Fails to launch with a combined sink

[VoidAny]

I ran this command: pactl load-module module-combine-sink and the program failed to start.

What that command does is make a combined sink output that outputs audio to every output sink when audio is played on it. When trying to start pulsemixer after running it, I got the following traceback:

Traceback (most recent call last):

I am using Artix linux. I am using pipewire and pipewire-pulse for pulseaudio emulation and wireplumber as a manager for pipewire.
