This may not make a lot of sense or may be common knowledge, but I thought I'd try posting here anyway.
My TV has a VGA input and I have a third-party VGA cable for my Dreamcast that comes with the red and white audio cables. Video works perfectly, but there's only one audio input. I can plug in either the red or white cable and sound will come out of either the left or right channel (forget which one is which). I don't believe I've seen this type of audio input anywhere if it's even input; what kind of converter would I need to get the two audio cables into one port like this? Would it be better to look into a VGA box?
