Doppler Effect removed from Chrome

In Chrome 55+ the function setVelocity has been removed. If your C++ game depends on OpenAL and somewhere you call:

alSource3f(mAlSourceId, AL_VELOCITY, …

alSource3f(mAlSourceId, AL_SOURCE_RELATIVE, ...

Then you should either remove those calls, but if your game depends on AL_SOURCE_RELATIVE and you cannot remove it, then it’s required to add a simple snipped to your HTML page:

// A stub for missing setVelocity in Chrome 56+
try {
	if (typeof PannerNode.prototype.setVelocity == "undefined") {
		PannerNode.prototype.setVelocity = function() {}
	}
} catch (e) {}

try {
	if (typeof AudioListener.prototype.setVelocity == "undefined") {
		AudioListener.prototype.setVelocity = function() {}
	}
} catch (e) {}

It’s required due an underlying implementation that sets velocity while you call set source relative.
