General Information

Sound forwarding relies on the same GStreamer libraries as GStreamer screencasting mode.
Because of that, it has the same limitations and is not currently available on Microsoft Windows.

Setup

In order to be able to use sound forwarding, you must ensure that the sound devices are configured correctly in the Sound tab of the Configuration dialog:

Application Sound Forwarding

Any application, seamless or not, can have its sound forwarded to the machine where it is being used, simply click on the sound icons to start or stop speaker and microphone forwarding:

Display Sound Shadowing

Sound shadowing allows the sound of an existing desktop session (a real one, not a virtual one) to be forwarded to another machine.
This requires that the desktop session uses pulseaudio, this is generally the case on many Unix-like operating systems, but not on Microsoft Windows or Mac OS X.

Plugins Used

GStreamer sound forwarding relies on the following plugins for buffering, sending and receiving the sound stream:

• gdp for payload
• queue for buffering
• tcp for transport

The following compression plugins are supported:

• vorbis: Vorbis Audio
• flac: Free Lossless Audio Compressor
• faac / faad : AAC Audio
