Greetings,

Probably a bug in my driver (asihpi), but I don't understand how "amixer controls" can work while "amixer scontrols" fails.

(with error code -EINVAL: "Mixer hw:1 load error: Invalid argument")

Where should I start looking for why this happens?

Simple mixer is code on top of standard control API. See alsa-lib/src/mixer tree.
