Audio takes time to start
When playing videos or sounds, the first few seconds are silent. This does not depend on the position in the video, I can scan through the media at random, but the sound will only start after around 5 seconds. After the sound started, it works flawlessly, but when sound is stopped for a few minutes, the same problem arises again.
Tl;dr: Sound takes time to "boot" and then "shuts down" after a while of not using sound, needing another "boot".
This happens with youtube and other HTML5 video players (streamcloud etc)

I'm on the latest Firefox (61.0.2) and running Windows 10 x64. I already found the articles you linked, but they didn't help.
Please try : SAFE MODE
- https://support.mozilla.org/kb/Safe+Mode
- https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
In Firefox Safe mode these changes are effective:
- all extensions are disabled (about:addons)
- default theme is used (no persona)
- userChrome.css and userContent.css are ignored (chrome folder)
- default toolbar layout is used (file: localstore-safe.rdf)
- Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
- hardware acceleration is disabled (Options > Advanced > General)
- plugins are not affected
- preferences are not affected
TEST''''is issue still there ?
I launched it in safe mode and the issue still appears. The sound starts after ~5 seconds.
Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
Just tried; In Safemode the same error occurs. Though I found a new symptom: The "cooldown" seems to include Firefox restarts. So if i restart firefox, sound works directly if it worked before (and then you can wait for it not to work when pausing).
