[pulseaudio-discuss] Map sink-input to virtual microphone

[guest271314]

A virtual microphone can be created using module-remap-source
https://aweirdimagination.net/2020/07/19/virtual-microphone-using-gstreamer-and-pulseaudio/

pactl load-module module-remap-source \ master=virtmic.monitor
source_name=virtmic \
source_properties=device.description=Virtual_Microphone

AFAICT a sink-input cannot be set as the source for the virtual microphone.

A sink-input can be recorded using parec or parecord --monitor-stream option

parecord -v -r --monitor-stream=26 --file-format=wav output.wav

How to set a sink-input as source for the virtual microphone so that the
output of the sink-input is still played back to speakers or headphones and
simultaneously is the source of the virtual microphone?
