Hi,

I'm observing high CPU loads after "new window.AudioContext()" calls (factor 50 on an i.MX6 Quad). The reason for this seems to be the "audiointerleave" GStreamer element. I did not see this on 2.30.3, but sound did not work back then in the affected application. The high load seems to affect all stables releases (at least) since wpewebkit 2.32.3 (I did not test 2.32.{0,1,2}).
