I am using nvidia. My PC connects to a TV that have sound. However, HDMI not showing up.
This is the screenshot
As you see in the screenshot in nvidia settings, if I go to set up digital audio I see that the nvidia software can detect my TV as sound device, which is LG M2341A.
However, HDMI doesn't show up.
The problem is it has shown up before.
No HDMI shows up in devices manager either
Notice it USED to work. One day my computer didn't work. Someone repair the power supply and it no longer works.
HDMI doesn't show up under in device manager under sound, video and game controller
I think that's the root of the problem. Perhaps someone delete it. How to turn it back on?
