Can't be done!
The sound card has one ADC (Analog to digital converter) than handles 2
channels.
The CD, Aux, Modem, Line, Mic, etc inputs are all mixed and fed to those 2
channels.
And unfortunately Lame can't break left and right into separate channels.
Here was my solution (we currently run 13 streams, I was shooting for 22
but put things on hold for a while):

Its a FreeBSD system with a PICMG backplane board. Had it seeing 11 cards
but it gets mega unstable at 7.
It would rock if there was a way to use one of the pro audio boards that
does 8 or 16 inputs, but FreeBSD would have to support breaking it out
into 16 DSP devices.
