HDMI no audio
January 23rd, 2020
I believe most motherboards with integrated HDMI only provide video, you’ll have to use an aux cable from your motherboard to your monitor for audio to work.
The problem, I believe is the HDMI audio device is not in the controlpanel/sound/playback window. It needs to be selected. This is a common problem with HDMI when using a GPU with no integrated audio controller.
