The EMU10K1 Chips work only at 48kHz and the SPDIF input is resampling the data to 48kHz whatever is the input sample rate (even if this is 48kHz). So it's not possible to do sample accurate digital copy from SPDIF-in. Most semi-pro audio cards support exact recording from SPDIF, the M-audio cards for example are well supported under Linux (the Audiophile is a good candidate if you don't need multiple IO).
