Whoops sorry; I mix them up constantly.
Thanks Mario

ARA and Lenovo ThinkBook 16 Gen 4+ ARA to the Quirks List
Lenovo ThinkBook 14 Gen 4+ ARA and ThinkBook 16 Gen 4+ ARA need to be added to the list of quirks for the microphone to work
properly.

This patch alone makes sense to me.

I think it should go in as is, but it prompts another idea to me I want to run
by
Mark specifically..
Should we just drop this whole file down to a much simpler DMI match
prefix like
this:
{.driver_data = &acp6x_card,.matches = {DMI_MATCH(DMI_BOARD_VENDOR, "LENOVO"),DMI_MATCH(DMI_PRODUCT_NAME, "21"),}},That would allow it to match all the Lenovo Rembrandt systems presumably
and
can stop touching the file. This only makes sense if every single Lenovo Rembrandt design uses a DMIC from ACP. I don't know if that's a valid assumption and I think
we
need Mark to confirm it.
The DMI match "technically" would match some of the Intel systems from
this
generation but this driver is only "loaded" on AMD Rembrandt systems, so I don't think
it's
a problem.
I love the idea but I'm a little hesitant as I don't know if I'll be able to confirm it authoritatively - I don't have particularly great levers to pull on for platforms outside the Linux program. I'll try - but I think chances of being able to reply yes or no with confidence are limited.
I think it's relatively low risk for breaking anything on this years platforms - but may get more interesting for next years. If needed can we then just quirk any platforms that come up that need the logic reversing or does that get really messy.
I can confirm the "21" match is going to be match a ton of Intel platforms. For the AMD platforms - will this be limited to Rembrandt only or will it affect any past/future generations?
This driver only loads on Yellow Carp (Rembrandt). It is not used for any other generations.
My hope is that with the _DSD supported in future programs that less of these quirks are needed too even for platforms now in your Linux program.
Short answer - I'll see what I can find...but no promises
OK, thanks.
