mbox from digidesign...help?


I would like to have s/pdif ins and outs on my computer that has none via USB so I went down to the local pro audio place and they sold me something called an M Box...I hooked it all up and the audio from my computer does not play through it...it comes with protools software and I am beginning to think that I bought the wrong box. I want to be able to play music in itunes and have a digital output.
Any suggestions?

I recently bought something similar called an M-Audio USB Audiophile DAC. I
had to turn my computer off, connect the device to the USB output. Then boot the computer back up. Then I had to go to preferences -- sound -- output -- and select the M-Audio device so the music would play through the USB instead of the headphone jack or the internal speakers. Then, I had to go to the general preferences and click on the device's logo and select the output I wanted, which was ANALOGUE OUT and "24 Bit." I clicked the checks OUT of all other boxes. Then RESTART the computer. Try that.
Here's a page that explains how to set up your mbox....

If you are into home recording at all, you have bought a great little unit. If not, then you probably should look for something else. The quality of the hardware on the MBox is really quite good for the money, but it is designed to operate in the Pro Tools LE environment, and while it can be done, Pro Tools isn't the cleanest interface for straightforward playing of music.
