about ADAT ;D I have to try to get those ADAT chip, the AL1401 and the AL1402. On the SBLive there is 4 I2S input left (there's also 1 I2S input used by a AC97 codec, and 2 SPDIF input). SO yes this 4 I2S input can be routed thru a ADAT decoder, and you will have a ADAT input :). There are also 2 I2S output, one used by AC97codec, and 4 SPDIF output. the 4 SPDIF output can be converted to I2S, so it can be routed thru a ADAT encoder chip and you have a ADAT output ;D By now we are working (Gilles, SmashTV and me) on the 8 inputs ADC board, which as 8 balenced analog input, and 4 I2S out put. This board can be plugged directly on the sblive, or can be used with a ADAT encoder. SmashTV told me that we can used CAT5 cable for the ADAT, instead of the classic optic fiber, because optic fiber driver are hard to find and expensive. If you have more questions I will be happy to answer ;)
