+# audio_toggle.sh
+
+Switch PulseAudio/PipeWire audio output sinks.
+
+## Usage
+
+```bash
+./audio_toggle.sh [OPTION]
+```
+
+## Options
+
+| Flag | Description |
+|------|-------------|
+| *(no args)* | Switch to the next available sink |
+| `--to <pattern>` | Switch to a sink whose name matches `<pattern>` (case-insensitive) |
+| `--prev`, `--previous` | Switch back to the previously active sink |
+| `--list` | List all available sinks with descriptions |
+| `--current` | Show the current default sink |
+| `--move-streams` | Also move existing audio streams to the new sink |
+| `--help`, `-h` | Show help message |
+
+## Examples
+
+```bash
+audio_toggle.sh                    # next sink
+audio_toggle.sh --to hdmi          # switch to HDMI sink
+audio_toggle.sh --prev             # back to previous sink
+audio_toggle.sh --list             # see what's available
+```
+
+## Notes
+
+- Sinks named `easyeffects` are automatically filtered out.
+- The previous sink is stored in `~/.cache/audio-toggle-prev-sink`.
+- Streams are not moved by default; use `--move-streams` to relocate them.

+# input-remapper-switcher
+
+Automatically switches [input-remapper](https://github.com/sezanzeb/input-remapper) presets on a per-game (or per-app) basis when used with the **Hyprland** window manager.
+
+## How It Works
+
+1. Connects to the Hyprland socket (`.socket2.sock`) and listens for `activewindowv2` events.
+2. On each window change, it grabs the focused window's **class** and **title** via `hyprctl activewindow -j | jq`.
+3. If either value matches a configured entry in the `PROFILES` associative array, it activates the corresponding input-remapper preset on your device.
+4. When an unknown window is focused, it deactivates the last active preset.
+
+> Uses `input-remapper-control` under the hood to start/stop presets.
+
+## Adding a Game Profile
+
+1. Find the window class or title of your game:
+   - Run `hyprctl clients` and locate the game in the output (class and title are listed for each window)
+2. Get the exact name of your input device:
+   - `sudo input-remapper-control --list-devices`
+3. Edit `input-remapper-switcher.sh` and add an entry to the `PROFILES` array (line 6):
+
+```bash
+declare -A PROFILES=(
+    ["Grand Theft Auto V"]="GTA"
+    ["steam_app_1151340"]="Fallout"
+    ["steam_app_1203620"]="Enshrouded"
+    # Add yours here:
+    ["Your Window Class or Title"]="Your Preset Name"
+)
+```
+
+4. If your device is different, update `DEVICE_NAME` on line 13:
+```bash
+DEVICE_NAME="Your Device Name"
+```
+
+## Usage
+
+Run the script manually or launch it at Hyprland startup (e.g., in `hyprland.conf`):
+
+```conf
+exec-once = ~/.config/hypr/scripts/input-remapper-switcher.sh
+```
+
+The script runs in the foreground listening for events — it does not daemonize on its own.
