i dont know what causes this. It is like this on some of my systems
and not others. Even without the switch though, the spdif input is
available as alsa hw:0,2. Getting apps to use this subdevice 2 is a
bit hit and miss. Some require the subdevice to be specified and some
(such as Jack i think) dont. Non-alsa apps are more tricky.
i wonder though if this should be reported as an alsa driver bug,
perhaps related to chipset revisions?

makes no difference as far as i can tell.

none that i know of.
