Using the fix stated by ghomem media.fragmented-mp4.gmp.enabled = true
solved the issue with Facebook. However this opened another problem, now instagram vides doesnt work. Reverting it back to media.fragmented-mp4.gmp.enabled = false And instagram videos works again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528268 Title: Facebook's HTML5 Video No Sound Since last Kernel Update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-docs/+bug/1528268/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
