Please upgrade...

... if alone because dmix'ing as I described in c't will not work with
this ALSA version and the Audiophile. ;)

Your problem probably is, that you are *not* recording from your
digital input, but from the device called "default", which arecord
uses by default. "default" corresponds to "plughw:0W unless you
changed something in asoundrc (but you didn't do this).

To record from digital-in you need to tell arecord about this.
"arecord --help" gives the needed options, "arecord -L" shows the
possible devices (but many more than you need) and "arecord -D NAME"
selects a device called "NAME".

Although I also have the Audiophile, I don't have any digital audio
gear, so I never tried to record from that and thus I don't know the
name of the digital ALSA device off-hand, but maybe someone else here

BTW: OSS emulation on the Audiophile can be a bit tricky sometimes
because of the chipset, so you should try to use ALSA wherever
possible with this card.
