    Would it be 100% correct to say UAD and DCH are basically the same thing? Just asking because Nvidia and Intel label their universal drivers as DCH while RTK seems to stay with UAD.

    Hi,

    Yes, it's correct :

    HDA = High Definition Audio
    HDA (@realtek) = Standard (@nvidia) = Legacy (@microsoft & @Intel)

    UAD = Universal Audio Driver
    UAD (@realtek) = DCH (@nvidia & @Intel now) = DCHU (@microsoft) = UWD (@microsoft & @Intel before)

    DCH/DCHU = Declarative Componentized Hardware Support Apps Universal API compliance

    UWD = Universal Windows Driver

    Realtek call Diagnosis tool for UAD as DCHUAppDiagTool, and DCHU folder on their FTP server contains UAD.

    Yes, Intel has already passed all its drivers in MSI mode by default, there was only NVIDIA and Realtek to pass in MSI mode (not by default).
