It doesn't really ignore the .asoundrc--it just uses a device name that
was configured by the ALSA developers instead of one configured by the
user. The spdif device is identical to the "digital" device in the
.asoundrc on the wiki (assuming the user properly configures the card
and device numbers as described in the comments), but it does not do
format and rate conversion, so it will /only/ work with 48kHz PCM (or
AC-3 or DTS) output.
