I am using gtk-recordmydesktop to record the video output to my desktop. However, the videos have no sound. All the tutorials I found regarding this involved getting sound recorded from a microphone, while I am interested in getting the sound output recorded. How can I do this? The official FAQ says “The solution is in your mixer’s settings. Keep playing with it ;).” which doesn’t clarify anything.
How can I get the sound output recorded, while being able to hear it myself also?

I managed to get it going with the steps on the Ubuntu Forums, for clarity here is what I did:
sudo apt-get install gtk-recordmydesktop pavucontrol
- Opened the Pulse Audio Volume Control dialog:
Applications > Sound & Video > PulseAudio Volume Control
- Opened gtk-recordmydesktop
- In gtk-rmd advanced preferences, “Sound” tab, set “Device” to
- In gtk-rmd start a recording
- In Volume Control goto the Recording tab and change the recordmydesktop entry to ‘Monitor of ‘
This is what seems to have worked for me.
All I had to do was change
pulse in by: Advanced button > Sound tab > Device:.
If you use Pulseaudio, there is a howto in the Ubuntu Wiki. It basically boils down to using the pulse audio mixer, to re-route the sound from its source to audacity where it is saved instead of the default output (which would be you speakers).
I had to use these settings in pavucontrol:
Configuration > Built-in Audio > Profile > Digital Stereo (HDMI) Output + Analog Stereo Input
Then it recorded the sound that was playing
The sound is not recording due to low input level. You can fix this from here:
- Go to sound application of settings. Then in there you will see input option adjacent to output.
- You have just to increase the level of input from zero to approx 35-40%. This is the best level as experienced by me.
- Now again go to
recordMyDesktopapp and start your recording.
It will work fine(at least it worked for me).
Changing my sound card device to “pulse” did not work. When I changed it to “default”, it worked.
Debian, kernel 4.9.0-8-amd64 from lspci -v: 00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09) Subsystem: Lenovo Broadwell-U Audio Controller Flags: bus master, fast devsel, latency 0, IRQ 48 Memory at e1230000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel
This is the first thing I got working on Ubutu 20.04:
sudo apt install vokoscreen vokoscreen
Then go to the audio settings and enable all pulse devices:
After that it just worked, captured both computer output and my voice on the microphone.
Kazam has a “Sound from speakers” checkbox that just worked on Ubuntu 20.04:
sudo apt install kazam kazam
Unfortunately the video recording was bugged on Ubuntu 20.04: https://github.com/hzbd/kazam/issues/9
This is an old question, but here it is for Mint 17.2:
- Open “Sound Preferences” -> “Input”
- Choose “Monitor of $YOUR_USUAL_OUTPUT_DEVICE”
- Record normally in gtk-rmd
This way you can avoid having the input switch recorded in the video.
Just remember to switch it back when you’re done!
This setting works for me. Choose Monitors in the Show: in Input Devices
