So you need to add a combine-sink by executing 'pactl load-module module-combine-sink slaves=,' in a terminal. Now that you have a null sink, you are able to have applications that play on your speakers and applications which get their audio streamed by obs, but currently you won't be able to hear those. Unfortunately you are not able to name this upon creation, but you can use pavucontrol to rename the device if you want. Type in 'pactl load-module module-null-sink'. This is an output device that will not output to any hardware but will be used by obs. Another hint is that it will say 'RUNNING' at the end instead of, for example, 'IDLE'. (The internal name will be similar to the human-readable one. Copy the name of your standard output device, you will need it later. You will now see the same devices again but this time with their internal name.

Open up a terminal and type in 'pactl list short sinks'. In my case, its human-readable name is 'Built-in Analog Stereo'. If you play some sound, you will be able to see which of these is active. Open up pavucontrol and select 'Output Devices' at the top. Next, you need to figure out the internal name of your standard output device. On Arch Linux and Ubuntu the package is simply called 'pavucontrol'. If you are able to use pactl for everything, you can probably do that, too. Here is how to do that on Linux using PulseAudio:įirst of all, you are probably going to need pavucontrol as a nice user interface to PulseAudio.

Sometimes you want to stream the audio of one application, but not the other.
