I am under the impression that with multiple sound cards you have the
issue of clock drift, the audio channels would eventually go out of
sync, and this would get worse and worse over time. When only one
sound card is being used, the application can sync the video playback
to the audio device, since video speed is not as evident a distortion.
With multiple audio devices with separate clocks, you would most
likely get annoying phasing and comb filter artifacts, if not a
distinct echo. There are firewire cards that can share a clock in
order to eliminate this problem, but I have not heard of USB cards
that share a clock pulse.
