Hi, The answer is that the Mac doesn't natively support general redirection of sound from one source to another, which can also connect input/output devices with programs, but you can add this functionality with free add-ons such as Soundflower, which used to be distributed with Rogue Amoeba's products (Audio Hijack Pro, etc.) or be downloadable from their freebies page, as well as elsewhere. There also used to be open source projects like Jack Pilot, and there are dedicated apps that support audio re-routing (among channels, devices, sound cards, and programs). At the lowest level something like Soundflower will let you route your audio to another device, but the original program was written as a simple re-direct (either 2-channels or 16-channels). I'll post a link to an archived post that discusses some of this by summarizing a bit of the discussion from the mac-access list from two and half years ago. "Re: Redirecting Sound from programs" http://www.mail-archive.com/discuss%40macvisionaries.com/msg48543.html
Note that the links given then may not be the ones you want to use now, but it was an excerpt from a fairly extensive discussion on the mac-access list at the time. I haven't seen discussions of similar scope on the macvisionaries list. The mac-access mailing list page is: http://mail.tft-bbs.co.uk/Mailing-Lists.html You might also join and send your questions to the Pro Tools Access list, which would handle the more professional queries: http://groups.google.com/group/ptaccess?hl=en_US HTH.
