I am on a Thinkpad W530 laptop, running Fedora 26 with the default gnome/wayland set up.
My browser is Firefox 54.0 (64-bit).
I recently installed a set of various updates for my software and system. Once the machine booted up again, I noticed that no audio could be heard at all despite the volume being up, and that various video formats (in either HTML5 or Flash) were no longer playing in Firefox. I took the liberty of downloading and network streaming previously unplayable videos (a WEBM and an MPEG file) in VLC and in both cases it ran fine, however there was still no audio. Nothing.
Nearly all GIF's play, and certain WEBMS's play i've noticed.
Nothing so far on Youtube or Twitch. The speaker icon is shown in the tab for these sites (as if something was playing) but nothing can be heard.

Any help would be greatly appreciated, thank you.

What does pavucontrol show for you as your output device?

pavucontrol says the speakers are the output device. I do have a pair of headphones, so I assume the output could be that as well if I plugged them in.

Issue seams fixed now. I tried to install the "GStreamer Multimedia Codecs - H.264" package from the software gui. (It was under Add-ons and further Codecs.) It hasn't given me any clear indication that it has successfully installed; the "Install..." button in the gui is blue just like it was before I clicked it.
In any case, i assume this is what fixed my issues, although I have no way of really knowing for sure. I can stream videos and listen to audio just fine.
If anyone knows how to ensure this particular codec is downloaded by using the terminal to install it, I think that'd be awesome. Thank you all!
