Configuring Sound on Linux/Pulse Audio/Remote server

RTP
RTP streams use multicast IP adresses like 224.0.0.56 (default) and UDP datagrams for transport. Multicasts are generally not allowed in Internet (blocked by ISPs). RTP is designed for low latency.

TCP
Only uncompressed audio is supported.

Configuring the Server
This process is rather simple. You will need to load module-native-protocol-tcp. You can optionally specify an auth-ip-acl to permit/blacklist anonymous connections from specific ips or IP ranges (to list more than one, separate by semicolon).

Configuring the Client
Simply set the environmental variable PULSE_SERVER to the destination and PulseAudio will redirect the stream over tcp to the provided destination.
