Linux Mint/cinnamon 22.3 No Sound Playing Videos (youtube, Rumble & Bitchute) With Mozilla Firefox

Me again! Finally got Linux installed on my 2nd machine - had a hard time as it would not install from any of the DVD's I had made. Finally loaded the ISO file to a USB jump drive and it installed. Liking it so far - easier to add software and my printer over windows/trying to find my disks or the network printer! Anyway my problem is no sound while watching online videos using firefox. I researched and printed/followed a bunch of things but still no sound? I do have sound for the various things like Linux mint starting etc as well as I just tried a saved youtube video off of a jump drive and I have sound. Any ideas on how to fix this? I haven't looked yet is there a different browser I should be using or am I missed a setting or extension I need?

 

Update! I installed Chromium and have sound now with videos. Still would like to get firefox working but at least I can use Chromium.

 

Thanks but tried that as I have muted tabs several times accidentally while selecting a tab!

 

Good here! Shows firefox at 100% but still no sound. Found a setting for auto play videos and audio which setting is allow all web sites audio and video!

 

In firefox check the little box in the circle of the pic I posted, and see if sound is blocked there. If so just click it and select unblock. This could be it. Hope it helps.

 

No sound isn't blocked there. And I noticed the permissions for youtube block audio and video setting in your picture which I have found and made sure it is set to allow audio and video! Thanks anyway! Anything is worth looking at but I can get by now since I downloaded chromium and sound works with it. Still would like to figure it out but can live with it now.

 

Have you had any luck getting sound on FF? IF not have you tried updating it to latest version (as well as Linux)? After that maybe trying to fully uninstall/remove FF and reinstall a current version of it?

 

No luck but I haven't been trying anymore. To be honest the machine is an extra and I haven't even turned it on for a long time till just now. It did 92 updates and still no sound on FF. I just use Chromium if I need sound. Thanks though for the advise. I am a computer hoarder and this is just one of many I have and I decided I wanted Linux on one of my machines hence this machine.

 

IF you want a Firefox based browser that is a little more privacy leaning, check out both Pale Moon and Basilisk.

I hear you. I'm also a vintage tech collector . I've been trying to fix and get some of my older gear going again as I had some crashes. And yes, playing with Linux, mainly Mint LMDE 7.
