VBAN for Linux

I've used Voicemeeter Banana and Potato for a long time to do advanced audio management on my various computers, including streaming audio from various computers in the house to my laptop and vice versa.

VBAN for Linux allows me to incorporate some older laptops (that have trouble running Windows but no problem running Ubuntu Desktop) into my various setups. Primarily I use a second laptop to stream Youtube or Udemy videos while I'm using my primary Windows laptop. Bluetooth headset is connected to the primary laptop and all other audio sources are sinked to it. 👍

Configuring Ubuntu 20.04 to sink audio and use vban_emitter to stream to a VBAN receiver

Preparing Pulseaudio

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

# use "pactl info" or "pactl list" to find the proper alsa_output interface
pactl load-module module-combine-sink channels=2 slaves=vbanmix,alsa_output.pci-0000_00_1b.0.analog-stereo

pactl set-default-source vbanmix.monitor
Running vban_emitter



vban_emitter --ipaddress=$IPADDR --port=$UDPPORT --streamname=$STREAMNAME --backend=$AUDIOBACKEND --rate=$SAMPLERATE
