First, you said HDMI, but then in reply to notherdude you said it doesn't work on "PC (VGA)". Are you referring to the physical connection or the input label name from your tv? Can you confirm you have an HDMI cable connection on both ends from computer to tv? I've connected HDMI out from discrete cards AMD and Nvidia and integrated video (AMD and Nvidia) on multiple PC, TVs, and surround sound receivers and have never had any issue, whatsoever, so let's make sure we're on the same page and we can probably figure this out quiet easily. Also, would you mind posting a screenshot of your audio control panel so we can see exactly what you're seeing?
Well at the moment I am away from my computer for a week. But basically, I have my PC/VGA cable plugged into my monitor going to my video card, AND the HDMI cable going from my monitor to my motherboard.
The reason I have the HDMI cable plugged in also is because I for some reason couldn't get sound to come through my monitor speakers and so therefore thought I needed perhaps a dedicated audio cable specifically for audio? I remember having an option for my headphones, which are plugged into the Mic and Sound coloured connecters in the back of my motherboard, and then what seemed to be always present "Digital Audio S/PDIF" which when I set to default, the levels move around as if there's sound, but there is no audible sound. Maybe it's because I am on VGA display input method?
Ok, it sounds like you're trying to use the HDMI for audio only, which won't work. HDMI audio can only be transmitted when there is a video signal as well, so using your VGA output from your card for video, and HDMI from your mobo for audio isn't going to give you any sound. I take it your video card doesn't have HDMI out. Also, you said your headphones are plugged into the Mic and Sound coloured connectors? If your monitor has an audio input jack (a headphone type jack) use that for your audio, and connect the other end to the light green jack on the back of your PC, from your motherboard. If your monitor does not have an audio input jack, and your video card doesn't have HDMI out, then your only option to use monitor speakers is going to be to use your motherboard's HDMI as your video output, and since it's already set to the default for audio, you should find that your audio will start playing, once that HDMI is carrying video. If I'm understanding your setup correctly, this should resolve your issue.
