I have a yellow adapter and have plugged my HD lead from that into my HDTV, Now im getting to see it but i have no sound? Ive tried everything and cant solve the issue, i spoke to the person who built it through email and his reply was;
Yes the definition of HDMI is High Definition Multimedia Interface, basically meaning AUDIO and VISIAL.
As long as you set the sound on the PC to the HDMI output that's the PC ready to send audio. Remember to TAKE THE SPEAKER CABLE OUT OF THE PC if you are trying to use the HDMI audio. If you have a speaker cable from external speakers in the back or front ports you will not be able to use the HDMI audio. You can only use one at a time.
Here is a simple explination of the HDMI connection and Audio from this as its a simple set up but as your research show LOTS of people have problems getting audio:
The graphics card given came with its ORIGINAL HDMI converter. This HDMI converter was supplied by ASUS the manufactures of the graphics card. The PINS on this converter are set to give audio from the graphics cards audio chip. If you use a 3rd party HDMI converter you need whats called an Internal SPDIF cable connected to the graphics card and then to the PCs SPDIF as the layout of the pins are different.
This Asus graphics card you were given card is supplied with its ORIGINAL HDMI converter which means you don't need the Internal SPDIF cable. This graphics card does not even have the SPDIF port on it as its ONLY supplied with all accessories needed. This is why its the best in its class and this is why you were given this before one of the cheaper ones.
If you buy one of the cheaper HD4850 graphics card you don't get all the accessories and this is when you need to use the Internal SPDIF. All the cheaper graphics cards have the SPDIF port due to this. This means you need to buy the cable, the converter and so on.
