(PulseAudio) Make Built-in Audio Analog Stereo loop another device > TLDR: How do I make Build-in Audio Analog Stereo loop another output device? ![enter image description here]( I want to isolate some sounds from my computer to only record those, but I want to still be able to hear everything. TeamSpeak > Built-in Analog Audio Stereo ^ Game > OBS > Game Audio goes to Build-in Analog Audio Stereo and my OBS Output Device > > TeamSpeak only goes to Build-in Analog Audio Stereo I can already change the program's device in PulseAudio, I just need to route my `obs` Output Source to my `Built-in Analog Audio Stereo` Source

So you want a new sink that can be selected for Games, which forwards to two other sinks.

Create a null sink:


pacmd load-module module-null-sink sink_name=games sink_properties=device.description=Games


and add two loopbacks from the monitor output of that sink to the sinks you want:


pacmd load-module module-loopback source="games.monitor" sink="name_of_built_in_stereo_sink"
pacmd load-module module-loopback source="games.monitor" sink="name_of_obs_sink


You can get the names with


pacmd list-sinks | grep name:


and omit the angular brackets.

Try on the commandline first, then add to Pulseaudio initialization files when it works the way you want.
