Hi Guys, i am not sure if my question is related to Graphik or to Sound Forum, maybe both or here under MacOSX. My Masterplan is to use FrontRow from my Couch and watch movies on a big screen. :mrgreen: Therefore i already bought one 10m HDMI Cable and an iPhone Applikation called RowMote (Replaces the Apple Remote). And I found a little Applikation (TV Row) which switches the mainscreen over to my second screen whenever i start FrontRow. Up to this all works fine - I push the Button on my iPhone and FrontRow starts on my TV. But i got no sound yet. :twisted: My Graphikcard is a MSI 9800GT Whisper with two DVI Outs. My TV is connected by a HDMI/DVI Adapter. The Graphikcard is also connected to my Motherboards (EP-35-DS4) SPDIF_O header by this little 2 pole wire. As far as i know it is possible to transmit Sound over HDMI, but is it possible by MacOSX, too? I cannot find any Configurations refering to differnet SoundOutputs. Anybody here who can help me further? Thanks a lot, Marco And yes, its not a real Mac, more an EFiX!
