E16 gen2 seems to be identical to E14 gen6

[uli42]

At least this official document treats them the same.

However, I vote for adding E16 machines to this repo

I have a ThinkPad E16 Gen 2 AMD and unfortunately they do not seem to be the same. I've followed the guide for the E14 gen6 AMD but cannot get the microphone to work no matter what I try.

Update: after some research (and lost days & sanity), the hardware of these machines do appear to be identical, except for one small detail: the product name.

The E14 is named either 21M3 or 21M4 depending on the specific variant, while the E16 is named either 21M5 or 21M6.

The microphone simply needs a quirk entry to be added to /sound/soc/amd/yc/acp6x-mach.c, and there are already patches adding this, such as:

• https://lore.kernel.org/all/20240807001219.1147-1-kfs.szk@gmail.com/
• https://lore.kernel.org/all/20240725065442.9293-1-tiwai@suse.de/

Looking at the current state of this file it is clear that 21M3, 21M4 and 21M5 are covered, but 21M6 (my model) is missing.

I've thus sent in a patch requesting to add this:

• https://lore.kernel.org/all/20250308041303.198765-1-thomasmizra@gmail.com/

I tested this patch locally and everything on the guide for the E14 gen6 also works on the E16 gen2.
