I'm not so sure. I've had quite a few people wanting to do this. One 
user even has a card where the analog comes out his speakers but the 
digital is connected to his HDMI output. For him, he can play a movie on 
his computer via HDMI and direct the movie's audio via the digital 
connector while still using his computer and wanting to output desktop 
related sounds there.

That's not an overly exotic setup IMO.

(normally HDMI sound comes from a different "card" in the examples I've 
seen in the past, so this one was an exception to me). This example was 
on IRC just the other day... just search your backlog for STAC and you 
should find it!

That example aside, I have seen several comments from other users 
wanting to use both at the same time, so I for one would really like to 
see this setup supported in pulse (despite not having the h/w to exploit 
it myself!).
