I tried the reddit post but i did not understand what this meant

One thing to pay attention here is that we use just youroutput without .monitor at the end. You can get its value from pactl info.

I tried running pactl info
but i did not see anything ending .monitor

so i got it working but how do i make it so that it is in stereo and automatically connects to the currently active audio output?

after fighing with it for a while i managed to make it automatic.

#!/usr/bin/env bash

# Create a virtual sink that can be set as a monitor
pactl load-module module-null-sink sink_name=VirtualSpeaker sink_properties=device.description=VirtualSpeaker

# Link it with a virtual source that is visible in pulseaudio apps like Zoom
pactl load-module module-null-sink media.class=Audio/Source/Virtual sink_name=VirtualMic channel_map=front-left,front-right
pw-link alsa_output.usb-Generic_USB_Audio_200901010001-00.HiFi__Line__sink:monitor_FL VirtualMic:input_FL
pw-link alsa_output.usb-Generic_USB_Audio_200901010001-00.HiFi__Line__sink:monitor_FR VirtualMic:input_FR
