pinging Rpi

[haku5hu]

When you boot a pi, you can ping it with the plugin. After you reset, load a sketch with audio, ping doesn't give a sound anymore.

Press the ping twice. When a device is reset, the audio amplifiers are turned off in the device. This is because the original boardsI made had noise which we had to silence when there was no sketch running.

You can disable the feature by changing the mute config value

if you look at run.sh, you can see default MUTE value is pin 27. Make it zero to disable mute amp feature
MUTE=27
