Question: is it safe to try booting temporarily with the x1p42100-asus-zenbook-a14.dtb
as a stand-in via dtbloader, just to get partial functionality / diagnostics, while
a proper devicetree for this model doesn't exist yet? Main goal is internal speaker audio.
Happy to test and report back — I have the hardware in hand.

Please take a look at #67 . Regarding sound: The current Vivobook S15 dtb assumes 4 speakers, Vivobook 16 has two. I guess its time to break out a separate Vivobook 14/16 dtb (2 speakers) and probably revert the S15 to 2 speakers, too (not convinced, but I don't have either hardware).

Okay I took a look again at a hi-res photo of the S15 interior. 2 speakers. Will revert to that, so from 7.1.2 on its 2 speakers again.
