# ReforgerEQ
PipeWire/PulseAudio helper for exposing Arma Reforger's 5.1 output on Linux.

This project has two parts to running:

- 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
- Arma Reforger through Steam/Proton
- Carla
- LSP VST Plugins

For the Carla EQ stage on Arch:

```bash
sudo pacman -S carla lsp-plugins-vst
```

## Normal Use (after first time install)


---

>### Optional - Install script as a callable service
>
> ```bash
>install -Dm755 reforger-eq ~/.local/bin/reforger-eq
>```
>`~/.local/bin` must be on your `PATH`. If the command is not found after installing, open a new terminal or reload your shell config.
>
>If you choose not to install it, you can refer to it by running like a standard bash script ie. `cd` to the project directory and use `./reforger-eq` to run. 

---

# Installation

Due to program restrictions on both Arma and Carla, there is a three part process to installing first time.

## Part 1. Expose Reforger 5.1 Channel

### First time install

```bash
reforger-eq up
# launch Arma Reforger manually
reforger-eq expose
reforger-eq restore
reforger-eq check
```


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.

### After installing

```bash
reforger-eq launch
```

If `launch` errors or times out, use the manual flow from first time install.


>If Reforger negotiates only `2ch`, restart the game and investigate manually with `qpwgraph`, `reforger-eq status`, and `pactl list sink-inputs`.

## Part 2. Open ReforgerEQ Carla

Open `reforger-eq.carxp` through Carla:

- Launch Carla
- Click on Open
- Open `reforger-eq.carxp`

>Recommended (optional) KDE one-click launcher for start menu:
>
>- Right click the start menu or open `Menu Editor`
>- Choose `Edit Applications`.
>- Create a new item.
>- Name: `Reforger EQ Carla`
>- Program: `carla`
>- Command line arguments: `/path/to/reforger-eq.carxp`

---

## Part 3. Carla Output Wiring

>If you want to use `qpwgraph` to do this step, feel free. Be aware that it (sometimes) won't auto-wire when ReforgerEQ Carla gets reset. Using Carla's patchbay means it will *always* link itself to what is saved in the .carxp file. 

Enter `carla`, click on the small tab `patchbay` and 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
```

Carla patchbay example:
>'Speakers' is a generic device, your device name may vary.

## Useful Commands

```bash
reforger-eq up       # create sink, save default, make 5.1 default
reforger-eq launch   # up, launch Steam app, wait for stream, restore
reforger-eq restore  # restore previous default, then expose Reforger
reforger-eq expose   # move running Reforger stream to the 5.1 sink
reforger-eq check    # report whether Reforger is 2ch or 6ch
reforger-eq down     # restore default and unload the 5.1 sink
```

## Configuration

```bash
REFORGER_EQ_SINK_NAME=reforger_eq_51
REFORGER_EQ_DESCRIPTION="ReforgerEQ 5.1"
REFORGER_EQ_APP_NAME="Arma Reforger"
REFORGER_EQ_STEAM_URI=steam://rungameid/1874880
REFORGER_EQ_WAIT_SECONDS=90
```

LFE is silent even when Reforger is outputting 6ch.
