Re: How do you start the audio service in bluez-utils 3.30-3

To get the audio plugin to load, you have to recompile with the
--enable-glib switch.

The Activate service call isn't helpful anymore. It used to return the bus
id of the audio service, but now the audio service is a plugin. So the
service you want is actually "org.bluez"

You don't need to call ActivateService anymore. Just replace ":X.Y" in your
dbus calls with "org.bluez"

I had to figure this out on my own since the documentation on
wiki.bluez.orgis outdated.
