Re the USB audio thing...
I got a £10 "laced" USB audio adaptor.... I plugged it into my Deneb, told AHI to use the USB Audio device, and away it went, first time. No problems at all. Any cheap USB sound card will probably work.
On 3.9 anyway. On 4.0 it's a different story, takes a bit of hacking to get that to work (but work it does).
