I just installed Ubuntu 16.04 a couple days ago.
I can't play facebook videos on firefox. When I click on the video the page just refreshes and nothing happens.
Ihave no extensions installed and I've already removed firefox and installed it again but the problem still persists. I also have a black screen on twitch, though the audio is fine. On the other hand, videos and twitch work on Chromium
What I've tried
- Re-installed firefox
- Re-installed adobe flash player (not sure if did it right)
- Restarted my computer
lspci -nnk | awk -v n='[0403]' 'p&&/^\S/{p=0}!p&&index($0,n){p=1}p'
,aplay -l
,pactl list short sinks
, andpactl list sink-inputs | gawk -v name=firefox -v RS='\n\n' 'index($0, name)'
? Please also make sure that the relevant audio channels inalsamixer
(terminal) orgnome-alsamixer
(GUI) have their volume turned up and aren’t muted. Thanks.dpkg-query -Wf '${Status;1} ${Package} ${Version}\n' 'gstreamer*-plugins-*' | awk '$1 != "u" && $2 !~ /-dbg$/ { printf("%s\t%s\n", $2, $3) }'
might help too.
