I have a problem with my c-port soundcard that I hope someone can help me with..

In the configuration menu, I can select GSIF or ASIO each stereo output pair (the card has 10 outputs). But if i choose GSIF for a pair of outputs to use Sonar together with Gigastudio, I can no longer record in Sonar (the audio engine wont start). I think it has worked before with the same soundcard, so I am a bit puzzeled...

thanks for any help!
