I found the same problem on Firefox Nightly 55.0a1 (2017-03-21) (64-bit) on Xubuntu 16.04.2. https://www.youtube.com/watch?v=aIprfNSMmMU

No problem is you access Youtube from a direct bookmark: you can skip.
Problem is fired when clicking another Youtube video in the proposed video on the right window  side.

Could you provide the pushlog from repo mozilla-inbound, it would be useful to find the regressing bug.

This sounds like a dup of Bug 1348432

bug 1348432 is fixed for me.

1.) I wanted to say that TeamSpeak 3 causes Pulseaudio on Debian Testing to mute VLC every time a new song starts. Sometimes this happens with Nightly too. I have to open the volume control and unmute Nightly.
2.) On specific tones in Nightly and VLC, pulseaudio begins slowly to die, this specific tones sounds creepy.
3.) Another exmaple: If a Nightly video finishes playing, the sound of a radio stream in VLC gets very loud for a second and it's back to normal then. This can also happen vice versa.

I have these problems even Nightly isn't running. Maybe we have undiscovered Pulseaudio bugs across all Linux distributions causing theese strange behaviors. Back then on Ubuntu I had this problems sometimes too. The only safe way for me to prevent such situations is to have only one application with audio output (shown in the extended volume control). Try it.

I believe Debian Testing ships PA 10.0, so you should already be on the latest release.

The default config that we ship mutes streams marked as "music" when a stream marked with "phone" role starts. That doesn't sound entirely like the problem you're facing, but see if `pactl unload-module module-role-cork` help.

I'm not sure I follow what this is, can you explain?

Should also not happen (and doesn't here).

Could you file a bug for each of these issues with a clear set of steps to reproduce and the behaviour you see at -- http://lists.freedesktop.org/listinfo/http://bugs.freedesktop.org/enter_bug.cgi?product=PulseAudio ?

(Good to have clarified https://bugzilla.mozilla.org/show_bug.cgi?id=1348432#c38 that this bug here is not one of pulseaudio.)

Yes

That helped :')
> I'm not sure I follow what this is, can you explain?
Can't describe it precisely. Maybe a problem with different kHz or some high tones. Seems a bit random. Can't remember if it's VLC-only.

I began with Jessie and upgraded to testing directly after the release of Jessie. Because I don't touched the default settings I didn't reinstalled testing yet. Will reinstall first, test it and look then into the bugtracker. Thank you! :)
