This difference is caused by different dB values used in iLive and computer recording programs. Remember, that dB is not an unit. It is only a suggestion, that measured values are shown logarythmically. iLive scale is just in dBs where 0dB on meter means +4dBu on output. It is scale typical for analog consoles. Maximum output level without distortion is about +22dBu, so it is 18dB on scale. Your computer shows values in dBFS (Full Scale) where 0 dBFS means the maximum value (which can not be exceeded in any way).
It means, that when you’re sending 0dB (dBFS) from your computer it is also a full signal in iLive, 18dB above 0 on meter. And when you’re sending 0dB from computer via S/PDIF you will get -18dBFS on your computers scale.
Of course real values can vary from those above, your recording program can show RMS value despite peak (few dB lower), I am also not sure is 0dB in iLive exactly +22dBu on output.
Please look for dB, dBu, dBV and dBFS.
