CentOS 7 Comments

With Firefox updated to firefox-78.3.0-1.el6.CentOS.x86_64, I cannot get sound from Firefox. I’ve tried restarting pulseaudio, also logging out and logging back in. No help. Other A/V apps work just fine. Downgrading to firefox-68.12.0-1.el6.CentOS.x86_64 makes sound work again. For now, I’ve excluded version firefox-78.3.0-1 from yum updates.

Anyone else seeing this? Any hints?

  • No problem here .. but as a reminder .. EOL for CentOS-6 is about 1
    month away (Nov 2020).

    That means , once we hit it, no more updates.

  • 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.

  • The Ubuntu-derived distros are much better suited to desktop. I run several of them, as well as CentOS 7 and 8. Ubuntu, Kubuntu (Ubuntu with KDE), Lubuntu, Debian, PopOS, and Zorin.

  • They all use systemd. If you’re running CentOS 6 to avoid that, you’re out of luck.

  • I can live with systemd. It’s the Gnome 3 UI that I can’t stand. I gave Mate a try briefly, but ran into some issues that I don’t recall just now. I’ll give it another try, but I may just give up and switch to Mint. The major issue for my doing that is the package manager, since I have several custom packages that are RPMs.
