[PATCH] ASoC: amd: yc: Add Lenovo ThinkPad E16 Gen 2 (21JN) to quirks

[Seiji Adachi]

Hi,

I have a Lenovo ThinkPad E16 Gen 2 (AMD Ryzen 7 7735HS) with machine type "21JN".
Currently, the internal digital microphone (DMIC) is not detected on Debian 13 (kernel 6.18).

Similar to the "21M5" model, this "21JN" model also requires a DMI quirk entry to enable the internal microphone.

Could you please add the "21JN" model to the quirk list in `sound/soc/amd/yc/acp6x-mach.c`?

DMI info:
- Vendor: LENOVO
- Product Name: 21JN

Thank you,

Seiji Adachi

Hi,

An update on this: I have just upgraded my system kernel to the latest available version, 7.0.13. 

However, the internal digital microphone (DMIC) is still not detected (`arecord -l` shows the same result as before). 

So the quirk entry for "21JN" is definitely still needed in the latest kernel version.

Best regards,

Seiji

Hi,

I am writing to provide an update regarding the internal microphone issue on Lenovo ThinkPad E16 Gen 2 (21JN-003SCD).

I have recently updated the kernel to version 7.1.8+deb13-amd64 (Debian trixie-backports), but the internal digital microphone (DMIC) is still not recognized.

Output of `arecord -l` on kernel 7.1.8:
**** List of CAPTURE Hardware Devices ****
card 1: Generic_1 [HD-Audio Generic], device 0: CX11880 Analog [CX11880 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Could you please check if the DMI entry for 21JN can be added to sound/soc/amd/yc/acp6x-mach.c?

Thank you for your help.

Best regards,
Seiji

Please submit patches following the process documented in
submitting-patches.rst, the formatting of the email is quite important
for tools to be able to process the patch.

You might want to look at b4 to send the patches, especially it's web
submission endpoint which avoids having to configure mail:
