Video without sound on some sites but work on another

more options

I have:

125.0 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

Video on Facebook plays without sound. The video plays, I see the image normally, but no sound. Video on Youtube works perfectly.

Fresh install without addons or plugins. Switching to "Troubleshoot mode" does not change anything. Youtube with sound, Facebook without sound.

Any ideas where to look?

Thank you, the issue is resolved now.

But it is very mysterious. I did not have ffmpeg at all, and I had libavcodec58 (newer versions of libavcodec are not currently available for ubuntu 22.04)

I did:

sudo apt install ffmpeg sudo apt reinstall libavcodec58

And after firefox restarted - everything started to work as it should.
