Lenovo Thinkpad T14s Gen 6 21M1CTO1WW



Hi all,

I noticed the same problem (undetected built in microphone) as this 
topic on my
relatively new AMD laptop :

<https://bugzilla.kernel.org/show_bug.cgi?id=218216>

Fixing the lack of microphone detection would require editing the 
acp6x-mach
kernel file :
<https://github.com/torvalds/linux/blob/master/sound/soc/amd/yc/acp6x-mach.c>

I believe the laptop model's manufacturer and product should be added 
to the
yc_acp_quirk_table with :

       {
               .driver_data = &acp6x_card,
               .matches = {
                       DMI_MATCH(DMI_BOARD_VENDOR, "LENOVO"),
                       DMI_MATCH(DMI_PRODUCT_NAME, "21M1"),
               }
       },


Here's dmidecode -t baseboard for reference :
