Do you have any other audio devices?

I had Firefox, and only Firefox, pushing audio to my non-default speakers, everything else went to the default set.

No other audio I fixed it one could say I deleted Palemoon with Iobit uninstaller removed all traces and then deleted the profile of palemoon Rebooted and installed Palemoon Version 27.6.2 copyed over the profile I had saved of that version. Now I got sound out of Palemoon on my desktop like before.
I have Palemoon Portable version 28.3.1 (the newset version) I tried it and it will not Produce and sound So Something is going on with Palemoon version 28 with it killing off sound

What Add-on are you using to download youtube vids ? Does it work ok with Facebook videos ?
I use Palemoon 28.3.1 and tested a Youtube download. It works fine with this Add-on which places a download button under L corner of video with resolution options. You can find from a Palemoon Get Add-ons search: Complete YouTube Saver 5.7.36.1 by Carlos Garcia. Good Luck
