User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170814072924

Steps to reproduce:

Firefox Version 55.0.2, 32bit in Windows 7 Pro 64bit.

Let's say I go here: http://www.nbcsports.com/live to watch the NASCAR race at http://stream.nbcsports.com/nascar/monster-energy-nascar-cup-series (anything will do): which does use Flash to play still. I am currently using Shockwave Flash 26.0.0.151.

Anyway, if I say the open Twitter https://twitter.com/ in another tab, the audio cuts in and out and stutters as the Twitter page loads.  

I does this in a new, clean profile as well.

I installed 52.3.0 ESR version running a separate profile ( "C:\Program Files (x86)\Mozilla Firefox ESR\firefox.exe" -p "esr" -no-remote ) using a profile I copied from the 54.0.1 version before updating it 55.0.2.  Anyway, this audio stutter stuff does not happen with it.




Actual results:

Audio cuts in and out in the NBC stream as the Twitter page loads.


Expected results:

At most the video in the video stream might pause but the audio should not cut in and out.
Component: Untriaged → Audio/Video: Playback
Product: Firefox → Core
Do you get the same problem when playing a YouTube stream?
Flags: needinfo?(bugzilla)
Can you please attach the information from about:support to this bug?
No, it does not do this with YouTube since HTML5 is being used.  Seems related just to Flash streams.

I'm going to call this a Flash issue. It is likely that we can't do much about it.
Component: Audio/Video: Playback → Plug-ins
Well, it doesn't happen in 57beta3 with latest Flash so perhaps this will just fix itself.
It still happens in 57beta6, just not as bad.
Flags: needinfo?(bugzilla)
Mark, if you can, we'd love to see a performance profile of this. 

https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem
Well, with 57beta8 and Flash 27.0.0.59 I've not seen the problem for the past two hours watching Fox Sports. Been watching https://www.foxsportsgo.com/event/271952/baylor-at-oklahoma-state

I've also not had crash in Flash either.  If I start seeing it again I'll install Nightly to test out that Performance Profile.

Thanks for the report back! Appreciate the help.
Status: UNCONFIRMED → NEW
Ever confirmed: true
Priority: -- → P3
Well, using 57beta10 now and looks like NBC Sports has changed to a HTML5 player.  Watching http://stream.nbcsports.com/nascar/xfinity-series?pid=37548

So, can't really can't test the Flash part now.  I'm glad they finally went to HTML5.
