As mentioned in the title, I'm unable to simultaneously record my headset microphone and my desktop audio when using SimpleScreenRecorder in KDE Neon 5.24.

In the "Audio Input" section of the recording settings, I selected "PulseAudio" as Backend, whereas for Source I've tried both "Built-in Audio Analog Stereo" as well as "Monitor of Built-in Audio Analog Stereo" (see below):

enter image description here

When selecting "Built-in Audio Analog Stereo", the microphone gets recorded but the desktop audio does not, while the situation is exactly the opposite when I select "Monitor of Built-in Audio Analog Stereo" (can record desktop audio but not headset microphone).

Does anybody have an idea of how to solve this issue?

  • Do you use pulseaudio or pipewire? You could create a virtual audio device where you mix the different inputs. Commented Mar 18, 2022 at 8:52
  • Note: you could also use OBS, which allows for more complex scenarios Commented Mar 18, 2022 at 9:07
  • @mashuptwice I've got pulseaudio. How do I create a virtual audio device? Feel free to expand your document into a full-blown answer if needed. Regarding OBS, I'm not sure I need all those features, but I'll try it if nothing else works. Commented Mar 18, 2022 at 10:42
  • I have the same issue recently. Monitor worked before but it doesn't work now. It didn't require any setting or the JACK installation described in the answer section below. Have you solved this issue? Commented May 5, 2022 at 2:16
  • @JonathanTse I have solved by switching to vokoscreenNG, which has fewer features than SimpleScreenRecorder but at least doesn't have that issue. Haven't tried following the instructions in the answer below though Commented May 9, 2022 at 20:07

I had the same issue, and I will explain how I made it work in my system step by step. I hope this can help someone else.

I will leave the links to some websites that were very useful.

The global idea is to install JACK to manage the audio, and bridge JACK to Pulseaudio to be able to control the audio volume.

Step1. Remove Pulseaudio from the system to get a clean JACK installation:

sudo apt-get remove pulseaudio 
sudo apt-get remove --auto-remove pulseaudio 
sudo apt-get purge pulseaudio 

Step 2. Install JACK:

sudo apt-get install qjackctl jackd2

These are: qjackctl/stable,stable 0.9.1-1 amd64, the user interface for controlling the JACK sound server jackd2/stable,stable 1.9.17~dfsg-1 amd64, JACK Audio Connection Kit (server and example clients) During JACK installation, a windows open asking to Enable realtime process priority. I answered yes. enter image description here

Step3. Once installed, execute JACK, and a graphical interface will open enter image description here

Step4. Re-install Pulseaudio and module-jack

sudo apt-get install pulseaudio-module-jack
sudo apt-get install pulseaudio

Step5. Install Cadence software to allow bridging Pulseaudio/ALSA with JACK

sudo apt-get install apt-transport-https gpgv
wget https://launchpad.net/~kxstudio-debian/+archive/kxstudio/+files/kxstudio-repos_10.0.3_all.deb
sudo dpkg -i kxstudio-repos_10.0.3_all.deb
sudo apt install cadence

Step6. Configure the system. Here is where you will need to play around depending on your system audio devices. On JACK, open settings (Setup...), and define your sound card. These are mine:enter image description here

enter image description here

Execute Cadence: Bridge ALSA/Pulseaudio with JACK enter image description here

Restart the system Step 7. Configure Simplescreenrecoder to listen to your device. Check that it is getting audio from the system and microphone enter image description here

Probably this will not work at the first time. Play around with the JACK and Cadence configuration.

Some links that helped me: https://www.thelinuxfaq.com/ubuntu/ubuntu-17-04-zesty-zapus/pulseaudio?type=uninstall https://www.maartenbaert.be/simplescreenrecorder/recording-game-audio/#recording-game-audio-and-microphone-at-the-same-time

If you need something different, or I missed a step, please comment. This is not easy, and having clear steps would help so many people.

Good luck everyone


I'm using PulseAudio on Ubuntu 20.04, and for me, it was just a matter of selecting the right audio device. This may depend on your hardware.
