Disabling audio engine

[ozRocker]

I recently did some work for a mate using Babylon.js http://www.aarontyler.com.au/blog/strayashrapnel and its basically a Wordpress page which contains iFrames to my 3D pages, so basically there are multiple instances of Babylon.js being loaded.  This worked fine on desktop but started breaking on mobile devices after about the 4th instance.  The problem was having too many audio engines.  I solved this by commenting out some code from the .js file

I removed this:

this._updateAudioParameters();

and this:

            if (this._audioEngine.canUseWebAudio) {
                this._outputAudioNode = this._audioEngine.audioContext.createGain();
                this._outputAudioNode.connect(this._audioEngine.masterGain);
                if (options) {
                    if (options.volume) {
                        this._outputAudioNode.gain.value = options.volume;
                    }
                    if (options.mainTrack) {
                        this._isMainTrack = options.mainTrack;
                    }
                }
            }

I'm wondering if there's a better way to do this.  I couldn't see how it was possible to load Babylon.js and disable the audio engine because the file would stop parsing as soon as it caused an error.

Something worth trying is running Babylon core.  Web audio is not included there.

interesting...I just noticed that.  Seems to be in the 2.3 version only

So I guess I can include the core then include all the other extras that I might be using as well.  Thanks for the heads up bro!

Interesting. I'm normally creating the audio context only if you're requesting to play a sound via a BABYLON.Sound instancing. Otherwise, I'm never creating an audio context. As far as I remember, I've put that logic starting with v2.2. Which version did you use?

Does the problem occur on iOS or Android (or both)?

You can indeed use also the core version where we've simply removed the audio engine references & code.

This was with Babylon 2.1.  I was getting problems with iOS.  Didn't test it properly with Android.  It was spitting out errors on the console about too many audio engines.  Was fine on the desktop browsers though.

I switched to using the core now and its working sweet
