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 stoped 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?
How to make sound works on Mozilla Firefox 52?
ubuntu;firefox;alsa;pulseaudio;lubuntu
Just instal pulse audio sudo apt-get install pulseaudio pavucontrol
