Yes, of course. Would be awesome. However, neither HAL nor ALSA
provide enough information about whether the SPDIF and analog outputs
are exclusive to each other or not.
If they are not exclusive (which is the case on most devices) we need
to be able to switch the output during runtime.
What has been on my todo list for a while now is a) the ability to
autoprobe which combinations of analog/digital/recording are available
and b) a way to be able to switch output ports a sink during runtime.
It's unfortunately not trivial to do. So please be patient.
