The secret to it that no on mentions is that you need to run sdpd as well. On another note, I am realizing I don't seem to know that much about the protocol.
On another note, currently pondering what it takes to get virtually routable OSS working. Virtual_oss works for a chunk of it, but does not work a constant sync as I can't retarget it with out killing it.
Sndiod was my next stop, but appears to be the same problem... plus no way to map OSS to sndio.
