there was no active flow.
but the mixer interface doesn't work whether or not there's a flow,
nor whether or not i have ReleaseDevice enabled.
i should add that this all works fine with an earlier nasd running
on a 2.4 (vs. my current 2.6) kernel and running on native oss
(rather than my current oss-on-alsa emulation, which is version 1.0.11).
stay tuned. i clearly have some more research to do. :-)
