You didn't answer my question about the process separation - do you use
the sip stack as a library or is it a separate process?

If it's a separate process, then the cleanest solution would certainly
be to fix the pulse plugin. Would you be interested in doing that? It
shouldn't be hard at all. The code can be seen here:

The "device" parameter is parsed in SND_PCM_PLUGIN_DEFINE_FUNC().
Parsing "sink" and "source" can be done in the same way. The "device"
parameter is used in pulse_prepare(). You would use the "sink" and
"source" in the same place.
