Hi all. Same problem as in this topic:

https://bugzilla.kernel.org/show_bug.cgi?id=216270

Is it possible to add my manufacturer and product?:

# dmidecode 3.5
Getting SMBIOS data from sysfs.
SMBIOS 3.4.0 present.

Handle 0x0002, DMI type 2, 15 bytes
Base Board Information
        Manufacturer: ASUSTeK COMPUTER INC.
        Product Name: M5602RA

I checked it on my laptop, adding the vendor and product into acp6x-mach.c fixes an issue.

arecord -l without fix:
