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.

=== Audio-Bork ===
Our current audio-device is being detected as a 'C-Media CMI8788' and it's semi-borked. It sometimes works perfectly, sometimes its only serving one amplifier, sometimes it doesn't work at all. At some point in time before a specific kernel or driver-update, the device was correctly identified as a Xonar DX1(?) card.

Sound

PulseAudio Volume Control

The front area of our space is equipped with a powerful sound system. Seven wall-mounted speakers (JBL control), accompanied by a subwoofer beneath the stairs are wired to four amplifiers located in the server room. hyperion is connected to them.

PulseAudio

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

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

Unser Web Interface

Zum Musikhören: Die Verstärker über http://dorfmap/ einschalten. Die Anlage ist an den Multimedia-Server angeschlossen, auf dem ein MPD als Jukebox läuft.

Anschließend kann die Musik zum Beispiel über unser Web Interface unter http://mpd/ gesteuert werden.

Da das Web Interface auf Einfachheit ausgelegt ist, möchtet ihr evtl. einen MPD Client auf eurem Gerät nutzen. Eine umfassende Liste gibt es unter http://mpd.wikia.com/wiki/Clients

  • Für Android sind MPDroid und MPD Control ganz gut.
  • Für PCs (Linux und Windows) taugen Cantata und GMPC
  • Das Apple-Universum hat leider wenig Liebe für MPD übrig.
