Thanks all. Interesting discussion, even if it has slipped a little off-topic.
I was just wondering, with it being the application which auto-connect, could you make a dummy Alsa device, join it with the device in use with zita-a2j-bridge and have this as the default System-1/2 ports which everything will auto-connect to, then use a Monitor
output of this to feed a DSP chain/rack which is connected to the real outputs (which can be done easily with the Persistent Patchbay.)
Would much of a performance hit be expected it this method was used? Any possible clock issues (as I guess a dummy device can't really be clocked I guess not.) What would the additional latency be (a full Jack round-trip added)??
Thanks again, Dale.

Thanks Paul. Yes I suspected it might be a relatively basic step
to have something fill in that data. That would be awesome.
Hopefully it could be done if it's ever finished in Jack-1 and 2.
the thing is, many times the user is in a better place than the software to name the ports. that's why i trended toward a JACK startup process where the user would supply the information
that would get pushed into the port metadata.
there's no way the driver knows that system:capture_1 is "kawaii k5000 left", but i do.
For Jack-2 I believe the meta-data support is currently just stubs,
as sletz has said. It appears in the headers but that's about it.
I think...
last i heard, falktx is now maintaining both jack1 and jack2.
Tim.
