If anyone has ever encountered a problem like this and either hit a wall or resolved the following situation, please share your ideas and experiences. I recently obtained a Mac mini to use with my Sony LCD projection television (model number KDF-E55A20). To connect the two, I used a standard DVI to HDMI conversion cable. The picture looks great. I have connected the standard audio output of the mini to the audio portion of the HDMI port (#6) on the television using a cable that changes from the audio-out to RCA (red and white) cables. (I'm sorry I don't know what the name of this sort of cable is, but I know it is very standard). The problem: I get no sound! To troubleshoot I connected my Powerbook G4 to the same HDMI port (using the provided adapter to connect to the same DVI to HDMI cable). Once I plug in the same audio cable as I tried to use with my mini, I get both picture and sound. It seems that the television inactivates the audio input component of the HDMI port if it picks up what it thinks is an HDMI input (since it is supposed to carry audio). BUT IT IS ONLY GETTING DVI! So the problem is not with the mini as it produces audio normally. There's a setting (hopefully not hard-wired) with the Sony to inactivate the audio-in on HDMI input. Any assistance would be greatly appreciated (even someone saying they've encountered this problem and that there is no fix... at least I can quit trying to fix it).
