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

How often does this happen? If this isn't reproducible, I'm afraid this isn't fixable either.

Comment 2 trondsg+bugzilla+freedesktop 2016-12-20 23:43:59 UTC

It happened once. But it could be related to bug 98863, which has happened to various degrees several times.

Maybe the same: I started Spotify and clicked play, but heard no sound. I went into pa volume control and changed output from analog stereo to core 1. Now I had distorted sound. I paused and resumed, and the sound was fine.
