Has anyone tested one of these yet. I would be interested to know if the audio channels are sent seperately or is there a headphone/audio out socket/jack on them. I have a projector which will accept HDMI and SVGA but the projector only has one speaker, i usually send from computer to projector using SVGA 20m cable from upstairs to down and the sound is from the computers sound card via cables to a 5:1 surround system. Also if there is any loss in sound if sent seperately i.e. out of sync with movie playing - but not too much of a problem as i use GOM Player to play my movies.
