im literally losing my mind here since updating teh graphics driver my soundbar gets no audio over HDMI at all.

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 soundbar. in Sound settings the HDMI device doesnt even appear, and in Device Manager i dont see a high definition audio device for the GPU anymore, it worked yesterday on the old MV43V/N VGA Driver... help? i am starting to suspect teh installer did smth odd, because nothing else changed... the soundbar itself works fine with a game console on teh next input.
