Possible fix for built-in mic no detection on HP Victus Laptop series

When I first installed Arch (more than a year ago) everything worked as expected except the microphone, I tested many things but what really worked for me was: Microphone does not work on the HP Victus 16-e1xxx. In there they state that adding

	{
		.driver_data = &acp6x_card,
		.matches = {
			DMI_MATCH(DMI_BOARD_VENDOR, “HP”),
                        DMI_MATCH(DMI_PRODUCT_NAME, “Victus by HP Laptop 16-e1xxx”),
		}
	},

into the variable:

yc_acp_quirk_table[]

of the file:

sound/soc/amd/yc/acp6x-mach.c

the built-in microphone of the HP Victus 16-e1xxx worked as expected. So, I decided to give it a try, I replaced the argument of DMI_MATCH to

DMI_MATCH(DMI_PRODUCT_NAME, “Victus by HP Gaming Laptop 15-fb1xxx”)

Which is the Product Name that appears on System Information

# dmidecode|grep -A2 System\ Information|grep Product\ Name:\ | awk -F'Product Name: ' '{print $2}' 

Then, I compiled the kernel, booted into it and it worked! I havent tested if it also work if you just load that specific module (I asume that it will) and also dont know which one really is... the output of

$ ls sound/soc/amd/yc/ | grep .ko

throws:

snd-acp6x-pdm-dma.ko
snd-pci-acp6x.ko
snd-soc-acp6x-mach.ko

I guess that its snd-soc-acp6x-mach.ko If I decide to test it, I will update this. I hope you find this post useful

Re: Possible fix for built-in mic no detection on HP Victus Laptop series

Hi, just got an HP Victus 15-fb2xxx and I've been banging my head against the wall for a good while now. I'm wondering if there could be a way to apply this fix other than going to the kernel's source and compiling it myself (which I guess is what you're doing?)
I'm kinda experienced using linux but have never delved into custom kernels or anything like that.

Re: Possible fix for built-in mic no detection on HP Victus Laptop series

Ok I did end up compiling a custom kernel just for this fix. I'm back to confirm it also worked for an HP Victus 15-fb2xxx. I did try just loading the module first and it didn't work on my end, did you ever get to try it?
