PulseAudio
Use PulseAudio for playback from your machine or MPD/MPlayer/XBMC on.

There are three output devices available:


 * 1) Laptop Lounge for listening, presentations and theatre sound
 * 2) Hackcenter for showing stuff in the back of the room
 * 3) Combined Output \o ALL the outputs, for general background music

Use on the following commands to create a remote sink on your machine:

pacmd load-module module-tunnel-sink server=hyperion sink=hackcenter

or

pacmd load-module module-tunnel-sink server=hyperion sink=laptop_lounge

or

pacmd load-module module-tunnel-sink server=hyperion sink=combined

Then, switch the desired stream to the new sink. Use can use pavucontrol for that.

Warning Remember to lower your playback volume before switching outputs to prevent damaging everyones ears.

ALSA
PulseAudio outputs over the usual ALSA devices. The default mixer settings are balanced for nice background sound both in the Lounge and in the Hackcenter. To override these, use the PulseAudio mixer interface.

Musik
Zum Musikhören: Die Verstärker im Serverraum einschalten. Die Anlage ist an den Multimedia-Server (hyperion) angeschlossen. Auf hyperion läuft ein MPD, welcher mit jedem üblichen MPD-Client bedient werden kann. Zusätzliche Musik kann per NFS hochgeladen werden, anschließend muss die Datenbank des MPD z.B. mit "mpc update" aktualisiert werden.
