I still have 3 CentOS-6 installations: 1 desktop, 1 laptop, and
1 virtual machine. On all of them, I get no sound from firefox-78.3.0-1
and have to downgrade to firefox-68.12.0-1. I've tried with all
add-ons disabled (Boy, youtube is a pain without adblock.) and
there is still no sound. I don't know what else to try.

I don't know what I'll do after CentOS-6 goes EOL. I absolutely
cannot tolerate CentOS-8.
