    Hardware device with all software conversions

Run:

java -cp lib/falco-${project.version}.jar ste.falco.PlaySound red-tailed-hawk-sound.wav plughw:0,2

Note that resource is relative to /sounds.

JMX configuration To enable JMX for remote management and troubleshooting, uncomment the relevant properties in bin/falco.

Note that to make it working java.rmi.server.hostname must be set to the hostname the device is reached by the rest of the network. For instance, in a home network, the name is usually something like mypi.local where mypi is the name provided during Pi set-up.

To change the hostname, use the command

sudo raspi-config

Choose Network options/Hostname and set the wanted name.
