In an environment where video display devices are available for simultaneous viewing, servers provide audio streams to user devices for listening. People may, thus, listen to the audio streams through their user devices while watching the video display devices. An application on the user devices determines which audio streams are available, and the servers may indicate which audio streams are available. The application sends a request to a server to transmit a selected audio stream. The server transmits the selected audio stream, e.g. over a wireless network in the environment. A variety of additional features are enabled by the interaction of the application and the servers.
