Well I've been hanging around the CBC Radio feed for a while and I've
had periods where the sound in full-duplex mode with vat-4.0b1a has
been nearly perfect -- but the background static does come back at
times. I also had times when apparently network conditions were such
that sound overall degraded -- no way around this of course -- and
in this case the full-duplex driver would do better than the half-duplex
driver.

Anyway, the background static that appears some of the time seems to
be some artifact of how sound is being fed to the card in full duplex
mode, ie., the half-duplex audio-voxware module doesn't seem to exhibit
this problem.
