I am currently using Ubuntu 16.04 LTS and I can get videos to play with sound on YouTube but all Facebook videos will not play or no sound. SiriusXM loads and plays but still no sound. I have checked and double checked everything, all volume controls are on. I am using the most current Mozilla Firefox. Its a THINK PENGUIN computer, basic model. I am lost as to what to do to get the Facebook Videos to play or how I can hear my SiriusXM radio? Any help would be appreciated.
Thanks, Chris
From Firefox's media codec support table:
To avoid patent issues, support for MPEG 4, H.264 and MP3 is not built directly into Firefox. Instead it relies on support from the OS or hardware (the hardware also needs to be able to support the profile used to encode the video, in the case of MP4). ... Linux since Firefox 26.0 (relies on GStreamer codecs) ...

From GStreamers plugin lists:
gst-plugins-ugly
lame — Encode MP3s with LAME
x264 — libx264-based H264 plugins
