I have my new MBP (merom) and want to hook up to pure 5.1 surround sound. My PC had a sound card that had 3 colored outputs that went directly into their respective channels for true 5.1 on my thundering logitech z-5500s. I want....I need it.....on my mac. Anyone know about optical out options for 5.1 on the mbp? I've heard talk that the headphone jack (which is optical out) can actually output 5.1 as long as it is received correctly...? Also, anyone know much about leopard issues with Griffin's Firewave? Looks like a nice device, but seeing as how it appears to only be compatible with OS 10.4, are there any other similar options?
