Ok, so buying such a card has no advantage.

I've now tried Skype directly with plughw:CA0106,0 which is my Audigy. Now 
without Pulse sound is fine. With pulse audio, sound stutters... Do I have a 
bad pulse setup or is pulse audio broken?

I have attached my ~/.asoundrc and daemon.conf from pulse it would be nice if 
you could say whether it is fine or not.

Thanx
