= Using the FFADO DBUS server =

''DBUS (or Desktop bus) is a message bus system. It provides facilities to launch applications on demand when their services are needed, for instance when a new piece of hotpluggable hardware has been added to the system. See http://www.freedesktop.org/wiki/Software/dbus.''

== Basic usage ==
Before you can use !FireWire audio devices with FFADO, the ffado-dbus-server must be running:
{{{
$ ffado-dbus-server &
}}}
(The "&" tells the shell to put the program in the background, so that you can re-use the shell to run other applications.)
This command should be sufficient in the standard case.

== Advanced options ==
If you have a more complicated setup with multiple !FireWire controllers or need debugging output, check out the advanced options:
{{{
$ ffado-dbus-server --help
Usage: ffado-dbus-server [OPTION...]
ffado-dbus-server -- expose the mixer features of connected FFADO devices
through DBus


  -n, --node=id              Only expose mixer of a device on a specific node
  -p, --port=nr              IEEE1394 Port to use
  -q, -s, --quiet, --silent  Don't produce any output
  -v, --verbose=level        Produce verbose output

      --usage                Give a short usage message
  -V, --version              Print program version

Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.
