On youtube (html5 player in SeaMonkey), when clicking a new video, I was
suddenly blasted with "noise" at a VERY high volume. Muting pulseaudio, pausing
the video, lowering PA volume, and resuming made the sound normal again. Then I
increased the volume with no problems.

This behaviour could seriously damage hearing.

PA package: 1:4.0-0ubuntu11.1
OS: Ubuntu studio 14.04
Device: Alesis core 1
Kernel: Linux ubuntu-studio 3.13.0-105-lowlatency #152-Ubuntu SMP PREEMPT Fri
Dec 2 16:52:00 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
