<hr />
<div>Music is run off <code>powernap</code>, since that's the computer with the speakers attached. <br />
<br />
Office staff/termcom/syscom permissions are required to play music in the office.<br />
<br />
We also have MPD available, however this method is rarely used after 2022. ''kids these days''<br />
<br />
==How to play music==<br />
<br />
# Run <code>ssh [watid]@powernap.csclub.uwaterloo.ca</code><br />
# Run <code>bluetoothctl</code><br />
# Type <code>pairable on</code> and <code>discoverable on</code> into the console to enable pairing and discovery<br />
# Connect to <code>powernap</code> from your device<br />
# Respond yes to all the prompts on the terminal from <code>powernap</code><br />
# Type <code>trust [device_mac]</code> to automatically allow audio from your device next time<br />
# You should be able to play audio like a normal audio device now<br />
<br />
==How to control audio server==<br />
powernap uses PipeWire and can talk to PulseAudio client. To set volume, mute some audio stream, or change output setting, use an office terminal and do:<br />
<br />
<pre><br />
PULSE_SERVER=powernap.csclub.uwaterloo.ca pavucontrol<br />
</pre><br />
<br />
If you're using a Linux laptop then this should work too.<br />
<br />
==MPD Controls==<br />
To view the keybindings of ncmpcpp, press F1 while it's running. <br />
The number keys switch between tabs in it. <br />
<br />
*1 is current playlist<br />
*2 is browsing files<br />
*3 is search<br />
*4 is browsing the media library<br />
*5 is browsing saved playlists, etc.<br />
<br />
You can add your own ''absolutely legitimately obtained'' music by copying them to <code>/music</code> on powernap. Then type <code>u</code> in ncmpcpp to refresh the database.<br />
<br />
==Termcom Info==<br />
<br />
*We require https://github.com/hrkfdn/mpdas to get scrobbling working as it "official" last.fm integration was removed from mpd in 2013. <br />
**n.b. https://github.com/hrkfdn/mpdas/issues/58<br />
*To control the mixer on other terminals, use <code>PULSE_SERVER=nullsleep pavucontrol</code><br />
*The official last.fm account credentials are stored in the exec password spot :)<br />
<br />
==Troubleshooting Playback==<br />
*Sometimes after connecting to powernap there is immense distortion and audio playback is not bearable.<br />
*To fix type <code>discoverable off</code> in the bluetoothctl environment (after a successful connection of course).<br />
*Current consensus is that this happens because there are so many bluetooth devices in MC that the compute on powernap gets overwhelmed.</div>Ysbirdihttps://wiki.csclub.uwaterloo.ca/index.php?title=Music&diff=5334Music2025-03-02T19:05:00Z<p>Ysbirdi: Added a Troubleshooting section for the Distortion problem</p>
