Unknown Multimedia Controller device after installing Windows 11 on a Huawei MateBook D14 AMD Laptop. Fixed by installing AMD Audio CoProcessor Driver.
The device Hardware ID is PCI\VEN_1022&DEV_15E2&SUBSYS_3E1919E5&REV_00
I tried installing the laptop drivers from Huawei's website - none of them were for the unknown Multimedia Controller device.
I also tried installing the AMD Ryzen Mobile chipset drivers, but this didn't have the Multimedia Controller driver either.
Solution: Install AMD Audio CoProcessor Driver for device ID PCI\VEN_1022&DEV_15E2
