A proof of concept here.

- Use case in this example is one sound for an andon call (need components, call team leader, etc) and one as an alarm when a barcode doesn't match.

- Two examples given for loading wav data from URLs or from file locations. Both load into the globals as a dictionary with keys 'call' and 'scan'

- Starting a sound will use `start('call')` or `start('scan')`

- Stopping a sound will use `stop('call')` or `stop('scan')`. Using `stop()` with no parameter will stop all clips.

```python
from java.io import ByteArrayInputStream
from java.net import URL
from javax.sound.sampled import AudioSystem
from javax.sound.sampled import AudioInputStream
from javax.sound.sampled import Clip

def loadUrls():
	''' Load a set of wav urls to the global dictionary '''
	
	urlDict = {'call': 'http://192.168.140.35/music/tv/GalaxyQuest.wav',
	           'scan': 'http://192.168.140.35/music/tv/scan_alert_short.wav'
	          }
	audioDict = {}
	for key, value in urlDict.items():
		AudioClip = AudioSystem.getClip()
		audioStream = AudioSystem.getAudioInputStream(URL(value))
		AudioClip.open(audioStream)
		audioDict[key] = AudioClip
	system.util.globals['audio'] = audioDict
	
def loadFiles():
	''' Load a set of wav files to the global dictionary '''
	
	fileDict = {'call': '/mnt/d/music/Andon music/GalaxyQuest.wav',
	            'scan': '/mnt/d/music/Andon music/scan_alert_short.wav'
	           }	
	audioDict = {}
	for key, value in fileDict.items():
		AudioClip = AudioSystem.getClip()
		inputStream = ByteArrayInputStream(system.file.readFileAsBytes(value))
		audioStream = AudioSystem.getAudioInputStream(inputStream)
		AudioClip.open(audioStream)
		audioDict[key] = AudioClip
	system.util.globals['audio'] = audioDict

def start(sound):
	system.util.globals['audio'][sound].setMicrosecondPosition(0)
	system.util.globals['audio'][sound].loop(Clip.LOOP_CONTINUOUSLY)
	
def stop(sound = None):
	if sound is not None:
		system.util.globals['audio'][sound].stop()
	else:
		for key in system.util.globals['audio'].keys():
			system.util.globals['audio'][key].stop()

```
