Then you run arecord and it records the sound from the multiple sources mixed together. The problem with the SB Live is that recording from the SPDIF is always interpolated to 48kHz, some interpolation happens between 48Khz input and the 48Khz of the sound card. In reality the sound quality does not change, but it does cause problems if you are trying to capture an AC3 or DTS signal, because the interpolation breaks it. A good program to test recording in is arecord, which comes with alsa.
