 Temporary PipeWire/PulseAudio 5.1 sink helper for testing Arma Reforger surround output on Linux.
 
-The goal is narrow: create a virtual 5.1 output device, make it the launch-time default, then let Arma Reforger decide whether to create a surround stream. Carla, QPWGraph, EQ, convolution, and long-term routing are intentionally manual follow-up steps.
+It creates a virtual 5.1 output device, makes it the launch-time default, then exposes Reforger back to that device after normal system audio is restored.
 
 ## Requirements
 
 - PipeWire with PulseAudio compatibility
 - `pactl`
-- Arma Reforger running through Steam/Proton or another Linux audio path that appears in PipeWire/Pulse

-After Arma has created its audio stream, restore your normal default device:

-
-`restore` first pins the running Arma stream to the 5.1 sink, then switches normal system audio back to the previous default device.

 ## Configuration
 
-Defaults are intentionally generic:
-
 ```bash
 REFORGER_SURROUND_SINK_NAME=reforger_surround_51
 REFORGER_SURROUND_DESCRIPTION="Reforger Surround 5.1"
 REFORGER_SURROUND_APP_NAME="Arma Reforger"
 ```
 
-Override them per command if needed:
+Example override:
 
 ```bash

-Good result:
+Good:
 
 ```text
 Sample Specification: ... 6ch 48000Hz
 Channel Map: front-left,front-right,front-center,lfe,rear-left,rear-right

-Stereo-only result:
+Bad:
 
 ```text
 Sample Specification: ... 2ch 48000Hz
 Channel Map: front-left,front-right
 ```
 
-If Arma creates a stereo-only stream, restart the game with the 5.1 sink selected/default before launch. Moving an already-created stereo stream usually does not make the game renegotiate surround.
+If Reforger negotiates stereo, restart the game with the 5.1 sink selected/default before launch.
 
 ## Notes
 
-- `up` temporarily routes normal system audio to the 5.1 sink until `restore` is run.
+- Prefer `restore` over manually changing your default output device.
-- `restore` does not unload the 5.1 sink; it pins Reforger if running, then gives normal system audio back to the previous default.
+- If you change default output manually, run `reforger-surround expose` afterward.
-- If Reforger follows the default sink when the default changes, run `reforger-surround pin` before switching devices manually.
+- `restore` keeps the 5.1 sink alive; `down` unloads it.
-- `down` unloads the temporary sink created by this tool.
+- LFE may be silent even when Reforger is outputting 6ch.
-- LFE may be silent in Arma Reforger even when the stream is 6ch.
