Use your phone as a mic for a Linux PC

1. 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.
Create a temporary virtual audio device
After a restart, the virtual device will disappear. You can follow these instructions to test AudioRelay.
Open a terminal window
Copy-paste this command
It creates a device where AudioRelay can stream audio into.
pactl load-module module-null-sink \
	sink_name=audiorelay-virtual-mic-sink \
	sink_properties=device.description=Virtual-Mic-Sink
Then copy-paste this other one
It creates a device usable by communications apps (e.g: skype). (It simply renames the Monitor of the previous device)
pactl load-module module-remap-source \
	master=audiorelay-virtual-mic-sink.monitor \
	source_name=audiorelay-virtual-mic-sink \
	source_properties=device.description=Virtual-Mic
What it should look like
​
​
Typing pulseaudio -k reloads PulseAudio and remove the temporary devices.
Create a permanent virtual audio device (recommended)
These are the same instructions as above but, the virtual audio device will persist between reboots.
Open the file  /etc/pulse/default.pa
Add these lines at the end
# 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

​
2. Start AudioRelay on your phone
Go to the server tab
Click on the microphone source
​
​
3. Start AudioRelay on your PC
Go to the player tab
Select Virtual-Mic-Sink as the audio device
Click on your phone in the server list
4. Start your communications app (Discord, Skype...)
Find the microphone settings
Select Virtual-Mic as an input device
