You should also check that sound card does not do resampling for sound streams from 44100Hz to 48000Hz (most common value). All emu10k-based sound cards DO resample ALL DSP inputs to 48kHz, even if you only need to send S/PDIF stream from CD S/PDIF to optical or coaxial S/PDIF output (I'm not shure are there any workarounds for this). envy24-based cards (from ESI, like Maya44 mkII or Juli@) may work 44100Hz streams without resampling to 48kHz, but I don't know are they supported in FreeBSD. They come for a rasonable price around $150, stereo input/output (balanced/unblanced line-level & S/PDIF, depends on card) only. And, of course, thare are "top" sound cards like Lynx Two, that will cost arounf $1500. Not supported on FreeBSD, as I know. For this card you will prefer to buy Mac or Windows :-( Yuriy
