HDMI and DVI are essentially the same thing, but with different connection and no standard for audio over DVI. Presumably you can even do HDCP over DVI if it doesn't need the sound are part of its authentication checks. -- |---------------------------------------/----------------------------------| | Phil Howard KA9WGN (ka9wgn.ham.org) / Do not send to the address below | | first name lower case at ipal.net / spamtrap-2007-12-15-0846@ipal.net | |------------------------------------/-------------------------------------|

So when you hook it to your TV with a DVI-to-HDMI cable, do you hear anything? -- |---------------------------------------/----------------------------------| | Phil Howard KA9WGN (ka9wgn.ham.org) / Do not send to the address below | | first name lower case at ipal.net / spamtrap-2007-12-15-1937@ipal.net | |------------------------------------/-------------------------------------|

The description from the page in a URL he gave elsewhere says an adapator is needed. That opens the possibility of, once the adapter is detected by the video card, changing some of the pin out usage from standard to a proprietary usage that the adapter is made for, such as audio over either the 2nd video port lines or the analog lines. -- |---------------------------------------/----------------------------------| | Phil Howard KA9WGN (ka9wgn.ham.org) / Do not send to the address below | | first name lower case at ipal.net / spamtrap-2007-12-18-2031@ipal.net | |------------------------------------/-------------------------------------|
