Issue with audio in unity3d loaded as WebGL

[ejoshva]

I am loading the unity3d as WebGL (i.e.) have got it as .html file. The graphics video plays without any niggle. But audio does not play.

Kindly let me know, if something I am missing to enable or add to make the audio play.

I am loading it on the QWebEngineView.

Environment : Mac 10.10

the audio format is OGG VORBIS.
Is there something, I should include in the .pro file to play this type of audio file.

Or some other codec needs to be installed in the webengine to play this audio format.
Is OGG VORBIS an allowed audio format to be played by QT
