Since a few months or so the HDMI audio driver for my RX 580 is not working anymore and I also can't install it by hand with the .inf file.
But the device ID is not the same in Windows 7 as the one in Windows 10 where it works...
In Windows 7 the ID is VEN_1002&DEV_AAF0&SUBSYS_AAF01458&REV_00 but in Windows 10 it's VEN_1002&DEV_AA01&SUBSYS_00AA0100, the DEV_ID is AAF0 on 7 and AA01 in 10.
In both Windows' the GPU and audio device are listed under the same PCI to PCI bridge in the device manager so it must be the same, no?
Any way to solve this? I tried older versions of the driver package but there the DEV_ID's in the .inf files don't match too so I cannot install them.
But it just couldn't have changed now, could it? It also works fine in Ubuntu with the same ID as in Windows 10.
