# reforger-surround
|
|
|
|
PipeWire/PulseAudio helper for exposing Arma Reforger's 5.1 output on Linux.
|
|
|
|
This project has two parts:
|
|
|
|
- Create a temporary 5.1 sink so Reforger negotiates surround channels.
|
|
- Manually open the Carla EQ project and wire it to your real stereo output.
|
|
|
|
Watching the graph in `qpwgraph` is recommended while testing.
|
|
|
|
## Requirements
|
|
|
|
- PipeWire with PulseAudio compatibility
|
|
- `pactl`
|
|
- Arma Reforger through Steam/Proton
|
|
|
|
For the Carla EQ stage on Arch:
|
|
|
|
```bash
|
|
sudo pacman -S carla lsp-plugins-vst
|
|
```
|
|
|
|
## Install
|
|
|
|
```bash
|
|
install -Dm755 reforger-surround ~/.local/bin/reforger-surround
|
|
```
|
|
|
|
## 1. Expose Reforger 5.1
|
|
|
|
Preferred flow:
|
|
|
|
```bash
|
|
reforger-surround launch
|
|
```
|
|
|
|
This creates the 5.1 sink, makes it default, launches Reforger, waits for the game audio stream, restores your previous default device, then exposes Reforger back to the 5.1 sink.
|
|
|
|
Check the result:
|
|
|
|
```bash
|
|
reforger-surround check
|
|
```
|
|
|
|
Good:
|
|
|
|
```text
|
|
Sample Specification: ... 6ch 48000Hz
|
|
Channel Map: front-left,front-right,front-center,lfe,rear-left,rear-right
|
|
```
|
|
|
|
If `launch` errors or times out, use the manual flow:
|
|
|
|
```bash
|
|
reforger-surround up
|
|
# launch Arma Reforger manually
|
|
reforger-surround restore
|
|
reforger-surround check
|
|
```
|
|
|
|
If Reforger negotiates only `2ch`, restart the game and investigate manually with `qpwgraph`, `reforger-surround status`, and `pactl list sink-inputs`.
|
|
|
|
Expected final QPWGraph wiring:
|
|
|
|
|
|
|
|
## 2. Open ReforgerEQ Carla
|
|
|
|
Open `reforger-audio.carxp` through Carla:
|
|
|
|
```bash
|
|
pw-jack /usr/bin/python3 /usr/share/carla/carla --with-appname=carla --with-libprefix=/usr /path/to/reforger-audio.carxp
|
|
```
|
|
|
|
Optional KDE launcher:
|
|
|
|
- Open the start menu.
|
|
- Choose `Edit Applications`.
|
|
- Create a new item.
|
|
- Name: `Reforger EQ Carla`
|
|
- Program: `pw-jack`
|
|
- Command line arguments: `/usr/bin/python3 /usr/share/carla/carla --with-appname=carla --with-libprefix=/usr /path/to/reforger-audio.carxp`
|
|
|
|
## 3. Carla Output Wiring
|
|
|
|
Carla patchbay example:
|
|
|
|
|
|
|
|
Wire Carla outputs to your real output device's playback ports:
|
|
|
|
```text
|
|
Output 1 -> playback_FL
|
|
Output 2 -> playback_FR
|
|
Output 3 -> playback_FL and playback_FR
|
|
Output 4 -> playback_FL
|
|
Output 5 -> playback_FR
|
|
```
|
|
|
|
## Useful Commands
|
|
|
|
```bash
|
|
reforger-surround up # create sink, save default, make 5.1 default
|
|
reforger-surround launch # up, launch Steam app, wait for stream, restore
|
|
reforger-surround restore # restore previous default, then expose Reforger
|
|
reforger-surround expose # move running Reforger stream to the 5.1 sink
|
|
reforger-surround check # report whether Reforger is 2ch or 6ch
|
|
reforger-surround down # restore default and unload the 5.1 sink
|
|
```
|
|
|
|
## Configuration
|
|
|
|
```bash
|
|
REFORGER_SURROUND_SINK_NAME=reforger_surround_51
|
|
REFORGER_SURROUND_DESCRIPTION="Reforger Surround 5.1"
|
|
REFORGER_SURROUND_APP_NAME="Arma Reforger"
|
|
REFORGER_SURROUND_STEAM_URI=steam://rungameid/1874880
|
|
REFORGER_SURROUND_WAIT_SECONDS=90
|
|
```
|
|
|
|
LFE may be silent even when Reforger is outputting 6ch.
