Comment 520 for bug 1958019

Just a heads up of my results so far:
Okay, so I compiled the latest Ubuntu unstable branch of 5.16-rc2 with a pull from Boonie: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound plus patches from Lucas: https://patchwork.kernel.org/project/alsa-devel/list/?series=585017.
(My fork over here: https://github.com/PIPIPIG233666/linux/commits/cs35l51)
I am using the Intel model as well and speakers do work out of the box but even with the amplifier fixes, I don't think the amplifier is working by any chance.

Tuning firmwares are present under Windows in C:\Windows\System32\csaudio while at it.
