S/PDIF Input level adjustment?

S/PDIF Input level adjustment?
Q:  I need to copy my DAT tape collection I recorded over a number of years to
    my computer hard drive and then to my iPod.  Your sound card included the 
    optical digital input I needed for this task.  My intent is to record via
    optical connection:  Digital out of my DAT recorder/player and digital in
    to my computer with no sound loss via analog conversion.  

    I have my original optical digital cable connected from the optical output
    of my Sony DAT recorder/player, connected to the Montego S/PDIF input.  
    A red light is emitted from the cable (sound card side) indicating to me 
    that a signal, indeed, is flowing through the cable.

    The problem ? I get absolutely no sound out of the Montego sound card.
    In fact, the Montego control panel doesn't even allow me to adjust the 
    sound volume on the mixer tab under the "record source" "SPDIF IN" under
    the "Record Settings."  (That option is grayed out yet it's the exact 
    option I want).  I note there is a SPDIF settings pull down menu under 
    the speaker tab "settings summary."  These appear to apply only to the
    SPDIF output which is not something I am using for purpose explained 
    above.  Nevertheless, I did experiment with different pull down settings
    (e.g. "S/PDIF Out 44.1") but that had no effect.


A:  You cannot adjust the S/PDIF input level that's why it is grayed out.
    S/PDIF data is digital data that is not adjustable. You can only turn it 
    on or off. You will not see any S/PDIF level on the LEDs until you start
    recording. 

    Please make sure that the Sampling rate complies to the following:
        The Montego DDL supports the following Sampling Rates for both 
        Playback / Recording (Input / Output) 

        44.100 kHz 
        48.000 kHz 
        96.000 kHz 

    The Sampling Rate is selectable in the Montego DDL control panel.
