I can do screencasts by pressing ctrl+alt+shift+r, but I get no sound when I view the videos, I've check my built in mic and headset, they both work on skype and such, I just can't record sound with the gnome built in screencasting. Also, when I open the videos in movieplayer they are in mute by default and there's nothing the the preferences I can find to change that.
Any help would be awesome!
This extension simplifies the use of the video recording function integrated in gnome shell, allows quickly to change the various settings of the desktop recording.
Active Shortcut: Super + E
NOTICE: If an error occurs during the update, is recommended to reload GNOME Shell (Alt + F2, r) and reload the extension's installation page.
I never heard that gnome-shell screencast record video AND audio.
In this case you can record with an another software in background or choosing an another application like recordMyDesktop.

Actually, you can record audio. You just need to re do the pipe in the config:
Paste this into a console and that should do the trick:
gsettings set org.gnome.shell.recorder pipeline "queue ! videorate ! vp8enc quality=10 speed=2 ! mux. pulsesrc ! audio/x-raw-int ! queue ! audioconvert ! vorbisenc ! mux. webmmux name=mux"
I found a solution that worked in my case. Open terminal Ctrl+Alt+T and run the following command:
gsettings set org.gnome.shell.recorder pipeline "queue ! videorate ! vp8enc quality=8 speed=6 threads=%T ! mux. pulsesrc ! audio/x-raw-int ! queue ! audioconvert !
vorbisenc ! mux. webmmux name=mux"
OR do it with dconf Editor, and then you'll have to modify the file: /usr/share/gnome-shell/js/ui/main.js in line 110 (I think) replace:
recorder.pause();
with
recorder.close();
After that, you can decide what stream of audio (internal or external) you want in recorder installing pavucontrol.
I hope that this would help.
According to Ubuntu Buzz - Unofficial Ubuntu blog you cannot record audio with build-in gnome-shell screencast.
This is one of great feature which is owned by the Gnome Shell, but one notable thing you should know is, you can't record any voice using this, you will get silent video

I searched and found another source. I don't know if this can be considered as more "Official". A relevant question to yours , about audio
On a related note, is it planned/allowed to be able to record audio as well as video?
answered like this
For sound you could just open sound recorder and start talking.

Of course all other answers here (with dconf editor & pipeline) are workarounds you can use.
