If more than one application is sending audio through an output virtual cable, VAC is able to mix all of the streams together or create separate corresponding virtual input cables. VAC is the audio equivalent of a MIDI loopback device such as MultiMid or Hubi, and can be used instead of 'Stereo Mix' or 'What U Hear' features of audio adapters. Since all transfers are made digitally, there is no loss in sound quality. Any application is able to send an audio stream to the input side of a 'virtual cable' while a corresponding application can receive this stream from the output side. Leave out the angular brackets when using the names as arguments.Virtual Audio Cable is a software product based on WDM multimedia driver that allows a user to transfer audio streams from one application to another. You can find out the names of all sinks, including the headphone sink, with pacmd list-sinks | grep name: For that, you need a loopback from the mentioned monitor source to the headphone sink: pacmd load-module module-loopback source='game_sink.monitor' sink='your-headphone-sink' That takes care of recording from group A only, but doesn't output it to the headphones. Each sink in Pulseaudio comes with a corresponding 'monitor' source (you can see those in the OBS menu you included), so setup OBS to record from 'Monitor of Game Sink'. Use pavucontrol or, if it can do that, the sound configuration of elementary OS to switch all group A sound outputs to that sink. Instead, create a 'null sink' on the Pulseaudio level: pacmd load-module module-null-sink sink_name=game_sink sink_properties=scription=Game-Sink Correct?ĭon't use snd-dummy, it works on the ALSA level.

Let me repeat: A single program or group of programs A (game) should output sound both to OBS and the headphone, while another single program or group of programs B (voice chat) should only output sound to the headphone, all on the Pulseaudio level.
