Pulseaudio Binding

This binding integrates pulseaudio devices.

Supported Things

The Pulseaudio bridge is required as a "bridge" for accessing any other Pulseaudio devices.

You need a running pulseaudio server with module module-cli-protocol-tcp loaded and accessible by the server which runs your openHAB instance. The following pulseaudio devices are supported:

• Sink
• Source
• Sink-Input
• Source-Output
• Combined-Sink

Discovery

The Pulseaudio bridge is discovered through mDNS in the local network.

Thing Configuration

The Pulseaudio bridge requires the host (ip address or a hostname) and a port (default: 4712) as a configuration value in order for the binding to know where to access it. You can use pactl -s <ip-address|hostname> list sinks | grep "name:" to find the name of a sink.

Channels

All devices support some of the following channels:

Channel Type ID	Item Type	Description
volume	Dimmer	Volume of an audio device in percent
mute	Switch	Mutes the device
state	String	Current state of the device (suspended, idle, running, corked, drained)
slaves	String	Slave sinks of a combined sink
routeToSink	String	Shows the sink a sink-input is currently routed to

Audio sink

Sink things can register themselves as audio sink in openHAB. MP3 and WAV files are supported. Use the appropriate parameter in the sink thing to activate this possibility (activateSimpleProtocolSink). This requires the module module-simple-protocol-tcp to be present on the server which runs your openHAB instance. The binding will try to command (if not discovered first) the load of this module on the pulseaudio server.
