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.

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.

Filme

Dockane stellt seinen privaten Beamer dem Chaosdorf zur Verfügung, die Fernbedienung liegt meist im Rollcontainer. Ein ausreichend langes Kabel baumelt an der Treppe rum. Beim Filmgucken kann über die Anlage auch der Filmton ausgegeben werden, dazu läuft auf Hyperion PulseAudio. Dies kann z.B. mit "mplayer -ao pulse:mpd film.avi" benutzt werden. Nach der Benutzung des Beamer bitte darauf achten, dass er ganz aus ist (d.h. Klappe vor der Linse zu).

Digicam

Der byte stellt freundlicherweise seine vor Urzeiten erworbene Canon Digital Ixus V dem Raum zur Verfügung. 128 MB CF-Card und zwei Akkus plus Ladegerät sind auch dabei. Liegt in der Verstärker/Telefon/Hauptswitch-Ecke. (Die Akkus sind allerdings beide ziemlich am Ende, jeweils 20 Bilder max.)
