I want to capture three (commonly clocked) I2S signals, that's 6 channels, onto a PC. If necessary, I can convert all into S/PDIF and capture those instead; it is quite easy to rig up a few S/PDIF transmitters. But I haven't been able to find anything that will capture the multi-channel digitial audio as either I2S or S/PDIF. Any ideas?
Oh good, and it's only a thousand bucks. Thanks, this would probably work, but it is not a realistic solution for me.
Maybe someone else has other suggestions?
I think some Creative cards have I2S inputs. Whether you can capture from them simultaneously, I don't know. But, multiple cards may be an option. I'm pretty sure my Turtle Beach Quadzilla used I2S for the optional S/PDIF input.
I'm in the same boat, but looking to capture 8 channels of I2S.
The most cost effective method I've come up with is multiple 2 channel cards. CMedia have a soundcard chip that should be able to do it, but there appears to be no commercial implementation.

There are no differences between the signals transmitted over optical or coaxial S/PDIF connectors—both carry exactly the same information. Selection of one over the other rests mainly on the availability of appropriate connectors on the chosen equipment and the preference and convenience of the user

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).
