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.  :-)
