    since updating teh graphics driver my projector gets no audio over HDMI at all.

    USB Audio Device Properties

    USB Audio Device Properties
Device status:
This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

    i tried another HDMI cable, another port, and restarting teh projector... in Sound settings the HDMI device doesnt even appear, and in Device Manager i dont see a high definition audio device for teh GPU anymore... it worked yesterday on the old GeForce Graphics Driver 368.22 Beta... help?? i am starting to suspect the installer did smth odd, because nothing else changed, the projector itself works fine with a game console on the next input.

    lol same thing happened to me in Device Manager, check Sound, video and game controllers for teh GPUs HD audio device. also try View > Show hidden devices. if its there but disabled, enable it. if its missing entirely, use Action > Scan for hardware changes.

    check the gaming monitor's input settings. some TVs and receivers renegotiate audio formats after a driver change. power-cycling the gaming monitor with teh PC on, or changing teh TV's HDMI audio mode to PCM, can bring the endpoint back. fingers crossed 🤞

    at this point my GPU cost more than my car lol

    yeahhh open the clsasic sound panel with mmsys.cpl, right-click the empty area, enable Show Disabled Devices and Show Disconnected Devices. A disabled HDMI endpoint wont appear in the modern Settings page. good luck man!

    i've seen Express install skip HDMI audio only when the previous install had it unticked. A clean install is the surest way to reset that.
