I have a HDMI running from my video card to my TV, and I did have sound working on my TV.
I must have changed some setting cause now I get only video but no sound on my TV.
Ive played around with the obvious, turned my computer on and off, plugged the HDMI into a different socket.
If I go into (audio device) under VLC, and set it from HDMI to my sound card, it works perfectly over my PC´s speakers, but not over HDMI when I put it back.
