Yes, you lose sample-synchronous guarantees. Also, there *might* be glitches
in the audio output of the ALSA apps using this technique, though its
unlikely to happen more frequently than if they were JACK apps.

the plughw:N device should take care of this. if not, alsa-devel needs
to know. i can use aplay to play stuff on my hdsp using plughw.
