# Online Gaming via Jitsi

Stream game and own voice to Jitsi and hear the other participants as well as the game sound.

* jitsi_sink input is used for everything that should go to Jitsi: output goes to JITSI-Meeting:
* That is game output (game sink output) and own voice (Microphone).
* game_sink should be the target of the game-source


```
# Once: find out how the devices are called:
pactl list short sources
pactl list short sinks

# Example: Vega
headphones=alsa_output.pci-0000_00_1b.0.analog-stereo
microphone=alsa_input.pci-0000_00_1b.0.analog-stereo

# Example: Sirius
headphones=alsa_output.pci-0000_29_00.6.analog-stereo
microphone=alsa_input.pci-0000_29_00.6.analog-stereo

# Use null-sinks as "aliases"
pactl load-module module-null-sink sink_name=jitsi_sink sink_properties=device.description=jitsi_sink
pactl load-module module-null-sink sink_name=game_sink sink_properties=device.description=game_sink

# Connect game and microphone to Jitsi
pactl load-module module-loopback source=game_sink.monitor sink=jitsi_sink
pactl load-module module-loopback source=$microphone sink=jitsi_sink
# Connect Jitsi to headphones
pactl load-module module-loopback source=game_sink.monitor sink=$headphones

# Manually connect Chromium (Jitsi) to $headphone in pavucontrol

# Adjust volumes - manually or like this:
#pactl set-sink-volume $jitsi_sink 100%
#pactl set-sink-volume $game_sink 100%

```

If pulseaudio sources have a `DONT_MOVE` flag it's not possible to change their associated sink. For some games like Deponia the solution is:

```
# Create a config file for openalsoft that allows the source to move
# but still uses the wrong default
# ~/.alsoftrc
[pulse]
allow-moves=yes
```

After the game you can unload the modules:

```
# Unload
pactl unload-module module-loopback
pactl unload-module module-null-sink
```
