Firefox tells me to install pulseaudio on a few (not all) yt/netflix videos. I have it.
Certain netflix and youtube (all the sites i've tested) videos don't play audio. For example, this: https://www.youtube.com/watch?v=Ii_Gz1WbBGA consistently doesn't work, but every other video I tried to replicate it on just now works fine.
Things i've tried: restarting firefox restarting computer updating pulse audio (am on the current repository version)
Thanks!

Do you have onboard or Audio card drivers installed and tested to see if you got sound? And what other codec did you install?
Just to be certain try https://www.youtube.com/html5/ as all check marks should ideally be blue.
You can also try the test videos at https://www.quirksmode.org/html5/tests/video.html
I have seen some Ubuntu users have issues with Firefox 57.0.4 and 58.0/58.0.1 packages with right clicking and middle-clicking issues so I would not be surprised if there could be a issue with their Firefox 58.0.1 build.

This is on Linux and not Windows. PulseAudio is needed for audio to work in Firefox on Linux since the Firefox 52.0 Release from Mozilla though some Linux distros may have delayed this change on their own compiled package builds.
