    I want to set the LED to turn on for the selected source.

    Is it possible?

  • JC

    When selected, the switch turns green.

    @JinGyu Choi Were you able to get this to work?  I'd like to do this as well.

    @Kevin Sporinsky It is possible without LED display. It is easy to do if you apply what I wrote.
