ASUS UM425IA shows headphones and speakers despite having no headphone jack

[Julian Sikorski]

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
