Asus Zenbook UX3402 speakers on Linux

I got the speakers working on my Asus Zenbook 14 OLED UX3402, the one with Intel CPU and the two CS35L41 audio amplifiers connected over SPI (not the UM3402YA, with AMD and I²C). The amplifiers are supported by the snd_hda_scodec_cs35l41 module in recent kernel versions, but they require some model-specific configuration paramaters, that should be provided by the BIOS, via ACPI. Of course, they are missing. It seems that the Windows drivers have those parameters somehow hardcoded, instead of using ACPI (bad idea, but who am I to criticise). Since Asus has been nasty and refused/was not able to update the BIOS with the missing data, I have patched the ACPI tables myself.
