  2. Start playing music on your device.

Normally that is all, if it does not play check the channel selector:

Set channel selector[edit]

  1. On the channel selector (the black box with rotary switch attached under the bar) make sure the flip switch is up.
  2. On the channel selector turn the volume about halfway.
  3. On the channel selector search for the right channel by turning the knob until you hear music.
  4. See #That didn't work for me if that didn't work for you.

  1. Make sure its 3.5mm AUX mini jack is plugged in.
  2. Start up the phone and let it play some music from your favorite service.

If problems:

  1. Check channel selector as above. See #Set channel selector.

From the Chromecast[edit]

  1. Make sure the beamer is on, the sound passes through that.
  2. Cast to the Chromecast using the Chrome browser: How to cast help page.
  3. Rest is same as above.

That didn't work for me[edit]

  1. Check the speaker amplifier, usually the amplifier itself should never be touched. Is it on? Is the volume about halfway? Set to AUX?
  2. Consider reading the #Troubleshooting: Detailed Instructions
  3. Oh darn, something's broken and there's nothing else you can do, you'll have to trace the audio path from source to speaker. Regardless if you manage to fix it, consider drop a word about it on Mattermost.
