Depending on how old your card is, it may actually be using HDMI TMDS 
transmitters on those DVI ports.  I had an issue with an nVidia 8-series 
card where the TV told the card it could accept audio, so the card told 
the TV it was sending audio (even though it wasn't), and the TV never 
tried anywhere else for input.  I had to feed the driver an EDID block 
with the extended data removed to prevent the card from sending an empty 
audio signal back to the TV.
