JJ provided beta firmware that increases the absolute volume output. It updates the D2 Audio chip on the board and has nothing to do with the driver which is the interface between the OS and the board (roughly speaking).
I know for sure that it never showed up as D2Audio for me in last one year. It has always been HD Audio Device. May be there is a BIOS update that is required.
Nothing happens when I double click on install.bat. When I run from command prompt this what I get.
C:\\Users\\srikanth\\Desktop\\D2Audio_X86\\x86>devcon update D2AudioHDAVista.inf "HDAUDIO\\FUNC_01&VEN_1A8D&DEV_1001&SUBSYS_FFFFFFFF"
Updating drivers for HDAUDIO\\FUNC_01&VEN_1A8D&DEV_1001&SUBSYS_FFFFFFFF from C:\\Users\\srikanth\\Desktop\\D2Audio_X86\\x86\\D2AudioHDAVista.inf.
I think the problem for the update failure could be because of hardware id. The hardware ids for the two HD Audio Device in my system are as follows:
I have tried changing the hardware id in the install.bat but that did not help either in getting the new drivers updated.
Anyway, I doubt if this has anything to do with the sudden failure of audio output. The only thing changed was a windows defender definition update that night.
Any further help?
