I'm using Ariff Abdullah's snd_hda driver on 6.2-RC2.
The driver reports:

I'd tend to that that the thing that stop the speaker when you plug in
the earphone is purely mechanical/analog electornic, it is not even at
the digital electronic level, your OS cannot detect that an earphone
has been pluged in, it is like your home stereo.
It ust be a feature of Acer!

A headphone plugged into a speaker line would blast your ears because of
the extreme difference in sensitivity unless the jack switches in a series
resistor to reduce the level. If you notice poor low-freq response in
your phones, that implies it is a line jack intended for an external
speaker amplifier.. -BobMc-
