It ended up having nothing to do with the dips, it was the new 740gt video card. As I left the dips the same to test and swapped the 9500 with the 740gt and could only get audio with HDMI. Swapped cards back and the audio worked again. Not a big deal, I ran a cable from the headphone jack on the TV to the audio input on the I/O board to get better sound through the machine speakers. In a perfect world I would like to have both audio through the tv and machine, but that doesn't seem possible.
