[SOLVED] Cant use mic on Honor MagicBook X16 2025

Bought new laptop.
The microphone is not detected by the driver:

I tried to mess with HDAJackRetask - no luck. There were many silent pins, few with random noise and one just copying output.
Installed win10 on VM with drivers from honor website - still nothing.
IDK much about how VMs work, maybe i should install win11 on real drive to make sure it isn't factory defect or something? Tho I'd be happy not dealing with this

Re: [SOLVED] Cant use mic on Honor MagicBook X16 2025

FIX:
get vendor and product id (HONOR and GOH-X)
add dmi match like this:

*** a/sound/soc/amd/yc/acp6x-mach.c
--- b/sound/soc/amd/yc/acp6x-mach.c
@@ -663,0 +663,7 @@
+	{
+		.driver_data = &acp6x_card,
+		.matches = {
+			DMI_MATCH(DMI_BOARD_VENDOR, "HONOR"),
+			DMI_MATCH(DMI_PRODUCT_NAME, "GOH-X"),
+		}
+	},

recompile kernel.
just curious if anyone knows why isnt it possible to autodetect such things or something
