Pulse Tunnel

The pulse-tunnel module provides a source or sink that tunnels all audio to a remote PulseAudio connection.

It is usually used with the PulseAudio or module-protocol-pulse on the remote end to accept the connection.

This module is usually used together with module-zeroconf-discover that will automatically load the tunnel with the right parameters based on zeroconf information.

# Module Name

`libpipewire-module-pulse-tunnel`

# Module Options

- `tunnel.mode`: the desired tunnel to create, must be `source` or `sink`. (Default `sink`)
- `pulse.server.address`: the address of the PulseAudio server to tunnel to.
- `pulse.latency`: the latency to end-to-end latency in milliseconds to maintain (Default 200).
- `stream.props`: Extra properties for the local stream.
