In the last several days (maybe up to 5), many Youtube videos no longer play sound. But not always. It APPEARS that the problem happens only when I skip playing an intro video ad. If I let it play, the problem doesn't happen. Here is an example of such video: https://www.youtube.com/watch?v=sSxtR4psOoQ Using 55.0a1 (2017-03-20) (32-bit) now.
I can reproduce on OS X with the testcase from comment #0. I hear sound on beta, but not on nightly.
