Hi,
I notice a bug report on Bugzilla [1]. Quoting from it:
> Hey,sound/soc/amd/renoir/rn-pci-acp3x.c has a hard-coded list of quirks. It seems like some product IDs may be missing. In my case, I am using a Lenovo Thinkpad t14s gen2 with an AMD Ryzen 7 PRO 5850U.

See Bugzilla for the full thread.

Hi,
thanks for your fast answer. I added my proposed patch as attachment.
Please be aware that this is my first kernel patch.
Thanks a lot!

Please don't top-post; reply inline with appropriate context instead.
Your patch is attached, please send it inline instead. See
Documentation/process/submitting-patches.rst for how to do that.
Thanks.

The kernel patch should be in a proper format, so that it can be
merged to the upstream. e.g. The Subject line should have a brief
description with the proper prefix for the corresponding subsystem (in
your case, something like "ASoC: amd:"). It'll follow the patch
description, as well as your proper Signed-off-by tag.
The details are found in
https://docs.kernel.org/process/submitting-patches.html
Could you resubmit the patch in a proper format?
thanks,
Takashi

Hi Oliver,
Did you forget Takashi's suggestion to follow formal patch submission
procedure [1]? Hint: It is suggested to use git-send-email(1) when
sending patches, as it handles them as-is (e.g. no wordwrapping,
tabs preserved).
Thanks.

The ThinkPad T14s Gen 2 latop does not have the internal digital
microphone connected to the AMD's ACP bridge, but it's advertised
via BIOS. The internal microphone is connected to the HDA codec.
Use DMI to block the microphone PCM device for this platform.
