OK, the OP already answered this, but we've discussed it here before with other nV solutions like the Zotac ones, and most of the new GTXs. Some with SPDIF headers, some with coax or optical sPDIF inputs. The HDMI can carry audio, but yes that is correct it is only SPDIF audio... which along with DRM is the limitation as to 2 channel LPCM or 5.1 DD/DTS not the passthrough + HDMI itself. You could always go the Azuretech solution route, but that's an added expense.
ResC you can do audio via DVI, and also the adapters don't offer significant degradation of signal, far less than even going from 6ft to 12ft of HDMI cable.
Anywhoo, kingqball, glad you figured it out. Always fun the quest for self-improvement or the realization, hey maybe I should RTFM, we all have those moments.
