The | 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. {{H|hyperion}} is connected to them. | ||
=== PulseAudio === | === PulseAudio === | ||
Use [[Wikipedia:PulseAudio|PulseAudio]] for playback from your machine or MPD/MPlayer/XBMC on {{H|hyperion}}. | |||
There are three output devices available: | |||
# ''Laptop Lounge'' for listening, presentations and theatre sound | |||
# ''Hackcenter'' for showing stuff in the back of the room | |||
# ''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 <tt>pavucontrol</tt> 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 [[Laptop Lounge|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. | |||
=== 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. | |||
