I have two systems.
One has network sound enabled, and auth enabled.
How I connect to that system via pulseaudio?
via zerocconf

Currently PA presents each soundcard as just two streams with only
volume, for example onn the desktop there are 3 record devices, a
subdevices of a single alsa device, but PA just sees the first.
also can you add to each stream besides the volume, the input source?


It would be great to have PA recording in skype.



Networking supports seems to be very basic (at least with padevchooser)

I could only connect to remote server and use it, but what if I want to
record from remote server, and play localy?

Also list of network servers doesn't seem to update often, and the
program crashes a lot.
