I use Lubuntu, which I believe does not use pulse-audio, or uses a container for that, I do not know, but it seems to use alsa well.

Since I upgrade to Firefox 52, which does not accept plugins anymore, the sound stopped working, and it shows a tip to fix that, but when I click on it, the site does not exist anymore.

How can I fix the sound on Firefox 52 without replacing alsa?

youtobe requires sound

tip do not exists

Firefox 52 comes built-in with pulseaudio as default sound output.

So on a system with alsa only, sound is broken on firefox 52.

You can either rebuild firefox 52 with alsa using --disable-pulseaudio --enable-alsa as compile option switches.

Or install pulseaudio if you dare!

  • AFAIK Lubuntu does use pulseaudio. Since there's no point of using ALSA in 2017 anyway, just do sudo apt install pulseaudio pavucontrol.

  • @dat-tutbrus maybe, sometimes appears PULSE*.log files on my home, I always delete these files.

  • dpkg --get-selections |grep pulse gives me libpulse-mainloop-glib0:amd64 and libpulse0:amd64 only.

  • I will try it in a VM, that is why I didn't answer yet, but even one of these solutions work, they are not what I expected.

  • The sound worked on qemu with pulseaudio installed, although I was not what I wanted to do, I am trying to rebuild firefox with alsa, but I cannot get it working, I will wait for Firefox working with alsa.

Try using Firefox ESR (Extended Support Release). It still supports plugins.

See https://www.mozilla.org/en-US/firefox/organizations/ for more information.

See https://www.mozilla.org/en-US/firefox/organizations/all/ for downloads.

  • @TiagoPimenta but can't you install your desired plugins into ESR?

  • I never installed anything to get the sound working, if it was a plugin it was built in. Maybe java works with ESR, but the sound still does not.

  • I was hoping that ESR still supported the pulseaudio that you need. Did you install pulseaudio?
