Subject: linux-image-6.12-rc6-amd64: Builtin microphone doesn't work on
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 :

# dmidecode 3.6
Getting SMBIOS data from sysfs.
SMBIOS 3.4.0 present.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
