Question

Does anyone know of a mini sterio with surround sound and optical input in Mac Mini form factor?
I use a Mini as the family media center and would like to have 5.1 or 7.1 sound for films but don't want a huge piece of eletronic equipment (I have one of those, but it isn't hooked up because it doesn't fit on the bookshelf). Years ago I used a PC and still use the Creative Audigy speaker system (Jimmy rigged to the Mini) that I ran from the PC. The Audigy PCI sound card obviously doesn't work on the Mini, so I just have two chanel plus sub. That has been fine since I switched to the Mini in 2007, but am updating to a new Mini in the summer and would like to upgrade my sound as well.
I also wouldn't be opposed to a USB soundcard that can drive the speakers. In fact, my wife would prefer smaller and less visible, ergo USB card hidden in the back.
Suggestions?

Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?
