Unless there is a new regression, Ephy should play HTML5 videos with the latest used volume, so volume shouldn't ramp up, even with flat volumes.

If YouTube sets the volume thru the JS API to 1.0 and that ramps up the volume, that's an expected behavior as per spec, and as per Pulseaudio flat volumes behavior. I won't discuss this any further as there was enough discussing in the other places, like bug 118974. I added a dependency to bug 140358 though as there is where we track the progress of the implementation of Pulseaudio's API.

Cyriaque, please tests with http://www.w3.org/2010/05/video/mediaevents.html and if volume works as I said there, then close this bug and subscribe to bug 140358.
