Capture 3x (6 ch) I2S or S/PDIF

[macboy]

I am currently looking into the M-Audio 1010LT. It has 8x 96kHz, 24 bit analog inputs and outputs. Each 2 channels of input & output is accomplished with a AKM stereo codec (ADC/DAC) with I2S interface. The 1010LT has a word clock input to genlock it to an external source. I figure I can rig up a way to bypass the ADC and feed alternate I2S bitstreams into the unit, using the genlock feature to synchronize it with my source. If that fails miserably due to clock issues, then I might consider throwing a ARSC in between my external I2S source and the 1010LT, which will resolve the clock issue at the expense of no longer having sample perfect capture, which I can live with I suppose. (The issue is due to the fact that the 1010LT will be generating I2S clocks - WCLK and BCLK - for its ADCs, but my I2S signals will also have their own WCLK and BCLK... If it can be very accurately genlocked to my source's WCLK, then it might work, but it might not).
