1.  How does a linux system normally access an SPDIF connection?  Would
this be through /dev/dsp1?  Or is it normally passed to the default
sound processor (/dev/dsp)?

2.  I fear my SPDIF connection won't allow _INPUT_ of signals?  I'd like
to use the optical connection to attach a friends minidisc, to record
his mixing onto my harddrive.

I have a card connected the three motherboard SPDIF pins, with two
external outlets-SPDIF and optical.  My motherboard manual says 'these
connectors supply an SPDIF audio cable that outputs digital audio'.  The
diagram indicates the three connectors are +5V, SPDIFOUT, and GND.

Doesn't look good does it?  Is this one of the reasons people end up
buying sound cards with oodles of connections?

For the record, the motherboard is an ASUS A7N266-VM, AMD Athlon 2200XP,
I'm running Debian 3.0r0/Linux 2.4.18.

TIA, Tim
