Add support for network sinks and sources

[ngiraldo]

I have setup a remote pulseaudio server, and added a pulseaudio tunnel in the local client.

The tunnel works and audio is emitted in the remote server.

I can select the tunnel as an output in sound settings "Tunnel to 192.168.0.20", but no selected or selectable entry appears in the indicator.

An interesting use case. Do you mind attaching the output of indicator-sound-switcher -vv (also interesting to see messages that are logged when you switch to the tunnel via Sound Settings)?

[yktoo]

Okay so that's the sink called Cincopuntouno, and it doesn't have any ports?

[ngiraldo]

Yep, I added the tunnel to the remote sound server as Cincopuntouno.

Do you need the output of another test?

[yktoo]

No, thanks.

A new version that supports network sinks/sources is pushed to dev. Please test if you can.

[ngiraldo]

Now I get this:

Traceback (most recent call last):
  File "_ctypes/callbacks.c", line 234, in 'calling callback function'

[yktoo]

It looks like you're still using the old indicator library. Try running it with:

PYTHONPATH=lib ./indicator-sound-switcher -vv

[ngiraldo]

It works perfectly.

[xmbwd]

I can confirm that the dev version works for network sinks, including Chromecast from mkchromecast.

Resolved in 2.2.0.
