flexible way of handling audio (alsa, oss, jack).
Actually, so does Myth; in libmyth there's a set of audio output classes with drivers for Alsa, OSS, JACK and more. Ed Wildgoose revamped this API and converted mythmusic to use it; that's the right thing for mythphone to do, to gain extra flexibility at very little cost. Perhaps this code would work for your needs in konference, at least for the output part of the problem.
I would be quite happy to recode it to allow input and output.
Having synchronised in and out audio will be essential if we ever want to support accoustic echo cancellation. I have been reading up on some algorithms, it's quite complicated though and there is no algorithm coded up (for free) that I can see. It's something of a special case of the room correction stuff that I use in my hifi setup though.
Will take a look as I get a chance
