OK I finally figured out that the custom edid option works but because I
was feeding the vizio from both the rbg and dvi ports on the card using
separate x displays I had 2 Device sections in the xorg.conf file. My
mistake was not adding the CustomEDID option to both of the Device
sections. Once I did so hdmi audio was disabled and analog audio worked.
In addition what appeared to be overscan in the DFP also was cleared up.
