I'm experimenting with WireTap Anywhere to see if I can stream live audio from various URLs to separate SoundIn/AuxIns in AM. I created a virtual device in WireTap with 5 sources and 10 channels of output. AM sees the virtual device as an audio driver, and maps the channels to SoundIn/AuxIn, and I think when I first tried it out, although an error window showed in AM, the audio was passed through. (I don't remember what the error was, but it could have been the same as below.) This happened a couple of times, as I was reconfiguring WireTap.
Then I had to leave it for a while. Now I get the error message: "A problem was encountered while activating an audio device: Internal PortAudio error (PortAudio error -9986"), and the audio won't activate in AM. This happens both with a preconfigured patch and with patching on the fly.
I managed to get this routing working with Reaper by selecting full duplexing for Reaper in the WireTap preferences, but that just seems to make AM crash. I can send the log files for those crashes. (Actually, I think it was crashing before I tried that, too, but I didn't save the earlier log files.)
Vital stats are:
MacBook Unibody 2.4GHz Intel Core Duo, 2 GB RAM, OS X 10.6.8
WireTap Anywhere 2.0.0
P.S. Right now, I'm only demoing WireTap (just as well!), so if there's another way to do this, I'd be glad to know. I know Soundflower doesn't work for this purpose, and I doubt Jack does.
