Well, qtwebengine doesn't link with PipeWire anyway, you have to 
use either PulseAudio or ALSA. Here is an example 
~/.config/alsa/asoundrc on my system, created by 
home-pipewire-service-type. If you add such file to your setup - 
qutebrowser should be able to use alsa lib to output audio through 
pipewire.
