Mbox 3 Pro and the 003 Controller.

If you have this set up, then I think you just need to set the 003 clock to "internal", not Spidf.

Ok That did it!! I have sound thank you. I wonder why the clock source in PT using the 003 would not let me choose spdif?

Ok this is a mixing AD/DA setup.

What would you suggest I do in a tracking scenario?

I would want to track through the Mbox.

If you set up the Mbox for AD/DA mode, then it should be ready to go.

You can just create tracks in Protools and select Spidf as the input. On a mono track, select Spidf Left or Spdif Right. On a stereo track, select Spidf Left + Right.

On your Mbox Pro, you should still be able to select Mic/Line/Instrument, etc., on inputs 1 and 2. If using a mic or instrument, adjust the gain just like normal.

Thats awesome! I did not realize that the sample rate changes automatically when an external clock source is selected in the control panel.

Follow nst7's instructions for using the two Mbox inputs.
If you used my standalone method of having the mbox still connected to the comp, you can use preamps 3-4 of the mbox as well as 1-2 (just not its conversion). In the control panel go to the tab for outputs 3-4. Bring up the faders for hardware inputs 3-4. Go TRS out of the Mbox outputs 3-4 to either 003 inputs 5-6 or 7-8. Now you have 8 pres while tracking through your 003, two of which have the Mbox conversion.
What about LLM? With this setup you can only use it with outputs 1-2 of the 003. I route all my tracks in my session to one master aux before the master fader. this way its easy to change the output of my tracks from spdif to analog 1-2 by only changing the output of the master aux and my recording tracks. you can also set the master aux to output through both the 003 outputs 1-2 and the spdif 1-2. Youre limited to using the 003's headphone outputs for tracking this way. Unless you take a cable from the 003 outputs 1-2(the ones separate from the monitor outputs) to the inputs 5-6 on the mbox(these are coax and 1/8" trs only) and hold down the speaker button until it flashes, to route inputs 5-6 to the mbox main outputs and headphones(if they are on the same stereo mix).
If you absolutely HAVE to have just the 4 channels of Mbox conversion, save your control panel preset. in pro tools select the mbox as the interface, and setup a new preset in the control panel according to how you will be tracking.
