I have a Deneb card and I believe that has a clockport...so that would probably be the easiest solution?
Yep, I would say its the best solution.
a Delfina is a sound card with hardware mp3 decoding. AHI drivers exist for a Delfina and all sound, including Paula and mp3 player output is funneled through the Delfina
The Delfina has AHI drivers cause its a sound card, they dont do any MP3 decoding, for that you use the Delfina.library, which is basically treated like the mpeg.library.
It also "funnels" the paula sound only because you hook a wire to the line input from Paula, you can do the same to your PCI soundcard.
Your PCI soundcard will always be better than the Delfina so stick with that.
