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

[Seiji Adachi <seiji_adachi@yahoo.co.jp>]

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
