ASUS UM425IA shows headphones and speakers despite having no headphone jack

Hello,

on ASUS UM425IA Pipewire reports having both speakers and headphones available. This machine has no headphone jack, it comes with a USB-C dongle (which I have not tested yet). Switching between the two changes the volume a bit - it is louder on speakers - but other than that audio plays regardless of what is selected. Headphones were selected by default. I have saved alsa-info.sh output here:

Thank you for your support in advance.

Best regards, Julian
