User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150105030202

Steps to reproduce:

The signal is connected to osc's parameter.
If the connected osc is stopped, the signal is forced to silent.

The code is here:
----
<script>
var actx=new AudioContext();

var oscA=actx.createOscillator();
var oscB=actx.createOscillator();

oscA.connect(actx.destination);
oscA.connect(oscB.frequency);

oscA.start(0);
oscB.start(0);

function test(){
	oscB.stop(0);
}
</script>
<button onclick="test()">test</button>
----
1) access to 
http://www.g200kg.com/demo/test/test-stoppedosc.html
2) press 'test'



Actual results:

the sound (from oscA) is forced to silent after pressing 'test' button


Expected results:

the sound should continue after pressing the 'test' button
