pulseaudio virtual sinks

below is a post found to stream music over skype. this can also be used to stream over teamspeak(tested).

pulseaudio module documentation

After many hours of tinkering I finally achieved it!

I created two Null Outputs and created two loopbacks for the first and one loopback for the second.

pactl load-module module-null-sink sink_name=Virtual1
pactl load-module module-null-sink sink_name=Virtual2
pactl load-module module-loopback sink=Virtual1
pactl load-module module-loopback sink=Virtual1
pactl load-module module-loopback sink=Virtual2

Next I opened PulseAudio Volume Control

pavucontrol

These are my settings. I typed them in the order they appear. Numbers go from up to down.

Recording tab

Applications:

All applications should input from your headset/microphone.

Except the application(s) you want to send the audio to should be set to one of the following. If you ONLY want to send the audio: Monitor of Null Output 1. It will be the first "Null Output" in the list. If you want to send both the audio and your voice: Monitor of Null Output 2. It will be the second "Null Output" in the list.

Virtual Streams

           Loopback to Null Output (1): Your headset/microphone
           Loopback to your headset/microphone: Null Output 1. It will be the first "Null Output" in the list.
           Loopback to Null Output: Null Output 1. It will be the first "Null Output" in the list.

Playback tab:

Applications:

All applications should output to your headset/speaker.

Except the application(s) you want to record/send through Skype/stream should be set to Null Output 1. It will be the first "Null Output" in the list.

Virtual streams:

           Loopback of your headset: Null Output 2. It will be the second "Null Output" in the list.
           Loopback of Monitor of Null Output (1): Your headset.
           Loopback of Monitor of Null Output (2): Null Output 2. It will be the second "Null Output" in the list.

just to not get confused with the "null Output", just specify the names like this:

pactl load-module module-null-sink sink_name=Virtual1 sink_properties=device.description="NAME HERE (mic+music)"
pactl load-module module-null-sink sink_name=Virtual2 sink_properties=device.description="NAME HERE (only music)"
pactl load-module module-loopback sink=Virtual1
pactl load-module module-loopback sink=Virtual1
pactl load-module module-loopback sink=Virtual2
