Summary: This card did not work in my computer. A computer repair store diagnosed the card as defective as one of its' chips was overheating. A second card sent by Amazon did the same thing. Gigabyte blamed the problem on my computer, first that I did not have enough power (bought new power supply) and then on the motherboard (too old). Amazon simply solved the problem and took the card back for credit. Thanks Amazon.
Summary: Avoid this card if you're expecting the HDMI connector to provide both video and audio. It just does video. You still need to use a sound card or other output from your computer to your tv or sound system.
