  ## Troubleshooting

  If you're having issues getting audio to work, here are some steps you can take:

  1. Make sure your audio devices are turned on and any hardware volume settings are on
  2. Open the Sound settings in System Preferences and make sure the correct devices are selected, and set Tuple to use the System Default
  3. Restart Tuple

  ## Using Tuple with Multi-line audio interfaces

  Tuple should enumerate all of the possible input options provided by your audio interface device. It will treat each line on the device as a separate input device that you can choose:
