Instructions

Create a virtual audio device

Other apps can't directly use AudioRelay as a source. We'll have to create a virtual audio device.

AudioRelay will send sound to this virtual audio device and other apps will listen to it as if it was a real microphone.

These are the same instructions as the temporary method, but the virtual audio device will persist between reboots.

# Creates a device where AudioRelay can stream audio into
load-module module-null-sink sink_name=audiorelay-virtual-mic-sink sink_properties=device.description=Virtual-Mic-Sink

# Creates a device usable by communications apps (e.g: skype)
load-module module-remap-source master=audiorelay-virtual-mic-sink.monitor source_name=audiorelay-virtual-mic-sink source_properties=device.description=Virtual-Mic
  • Open a terminal window
  • Type pulseaudio -k to make PulseAudio reload the file.

Result in Volume control

What the result should look like in Volume control / pavucontrol

(Installed via sudo apt install pavucontrol)
