Just open your command shell and execute this command

ffplay -nodisp -ac 2 -acodec pcm_s16le -ar 48000 -analyzeduration 0 -probesize 32 -f s16le -i udp://0.0.0.0:18181?listen=1

This command will listening ffmpeg server that hosted in localhost from VM with 48kHz bitrate.

Server Side

1. Set Null Output with sink name remote.

pactl load-module module-null-sink sink_name=remote 

2. Launch ffmpeg streamer, catch the sound from remote sink, and stream to WSL2 bridge ethernet.

IP_ROUTE=$(ip route list default | awk '{print $3}')
ffmpeg -f pulse -i "remote.monitor" -ac 2 -acodec pcm_s16le -ar 48000 -f s16le "udp://${IP_ROUTE}:18181"

Some tips: If you want to use this command for startup, stall the process using & after ffmpeg command.
