Configuring Sound on Linux/Pulse Audio/Remote server
RTP
[edit | edit source]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.
Server
[edit | edit source] $ pactl load-module module-rtp-recv
Client
[edit | edit source] $ pactl load-module module-rtp-send
TCP
[edit | edit source]Only uncompressed audio is supported.
Configuring the Server
[edit | edit source]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).
$ pactl load-module module-native-protocol-tcp auth-ip-acl=192.168.1.138
Configuring the Client
[edit | edit source]Simply set the environmental variable PULSE_SERVER to the destination and PulseAudio will redirect the stream over tcp to the provided destination.
$ PULSE_SERVER=192.168.1.146 totem
