HD-DAI, custom wiring project, need help!

[lankete]

Ok so heres the deal, I have a ps3 with HDMI input, A monitor with DVI output, and a pair or razer barracuda 5.1 surround sound gaming headphones with HD-DAI connector (identical connector as DVI but transmits audio). What need to do is have the headphones and monitor split into one HDMI cable into the ps3. It seems HD-DAI is exclusive to razer and not a mainstream form of trasnfeing audio. What i want to do is try to merge the HD-DAI cable with an HDMI cable as HDMI tranfers audio and is more mainstream (there are HDMI splittles i can use). So what i need to know is that is what i want to do possible? any pointers, or confirmation or workarounds to this situation would be greatly appreciated, thanks guys!
