    I recently purchased a set of Logitech Z-5500 speakers. I have the proper optical cable, and all my speakers are set up properly. For whatever reason, I can't get 5.1 to output from my Macbook Pro when using iTunes.

    Audio MIDI Setup is currently set to 44100.0 Hz 2ch-32bit digital output. I can't change it to 5 channel. (I don't know anyone who has to, anyway.) Any ideas?

    the movies you purchase from iTunes are 5.1 AAC, your speakers only support AC3 (dolby digital) and DTS.

    the only program that i've found that does on the fly conversion from AAC to AC3 is plex, but it won't play videos with DRM from iTunes. (not sure if it's included on all movies or not)

    Strange.. for my Z5300-E all I had to do was plug in the front speaker cable (Green) into my MBP headphone jack and I get full 5.1.
