Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36 Example URL: https://www.youtube.com/watch?v=3gxNW2Ulpwk Steps to reproduce the problem: 1. Visit https://www.youtube.com/watch?v=3gxNW2Ulpwk. 2. Begin playing the audio. 3. Start rapidly scrubbing the volume and observe a clipping sound in the audio stream*. What is the expected behavior? I expect to be able to rapidly scrub the volume with no audio artifacts. What went wrong? Scrubbing the volume for HTML5 audio and video elements causes popping sounds. Did this work before? N/A Is it a problem with Flash or HTML5? Both Does this work in other browsers? Yes Chrome version: 52.0.2743.82 Channel: n/a OS Version: OS X 10.10.5 Flash Version: Shockwave Flash 22.0 r0

That makes sense. Honestly I'm a bit naive on the implementation details, but applying smoothing to volume adjustments seems to make sense to me, since there's probably advantages to having volume adjustments be instantaneous, and in my case I'd like to implement some audio fading that sets discrete volume values during a short interval and have the audio output appear smooth.

Generally we'd recommend WebAudio for such work. I don't think we'll make any changes here any time soon. I can look next week to see if there's any bugs in the implementation though.
