# Mix

On **Fedora 43**, you don’t install “virtual drivers” the Windows way.
With PipeWire (which Fedora uses by default), you create **virtual devices (nodes)** such as sinks (outputs) or sources (inputs). These act like Voicemeeter’s virtual inputs/outputs.

Below are the main methods — from simple to advanced.

---

# ✅ Method 1 — Create a Virtual Sink (most common)

This creates a **virtual output device** that applications can send audio to. You can then route it wherever you want.

### 1️⃣ Create the virtual sink

```bash
pactl load-module module-null-sink sink_name=VirtualSink sink_properties=device.description=VirtualSink
```

You now have a new output device called **VirtualSink**.

---

### 2️⃣ Create a virtual microphone (optional)

If you want something like a “virtual mic” (for Discord/OBS):

```bash
pactl load-module module-remap-source master=VirtualSink.monitor source_name=VirtualMic source_properties=device.description=VirtualMic
```

Now **VirtualMic** appears as an input device in apps.

---

### 3️⃣ Make it persistent (survive reboot)

Create this file:

```bash
mkdir -p ~/.config/pipewire/pipewire-pulse.conf.d
nano ~/.config/pipewire/pipewire-pulse.conf.d/virtual-devices.conf
```

Add:

```ini
context.modules = [
  { name = libpipewire-module-null-audio-sink
    args = {
      node.name = "VirtualSink"
      node.description = "VirtualSink"
      media.class = "Audio/Sink"
    }
  }
]
```

Then restart PipeWire:

```bash
systemctl --user restart pipewire pipewire-pulse
```

---

# 🎛 Method 2 — Use a Patchbay (Graphical Way)

Much easier if you don’t like CLI.

Install:

```bash
sudo dnf install qpwgraph
```

Launch:

```bash
qpwgraph
```

You can visually connect:

* App → Virtual Sink
* Virtual Sink → Hardware Output
* Virtual Sink → OBS / Discord

## 🔌 Helvum (simpler UI)

Install:

```bash
sudo dnf install helvum
```

Very simple drag-and-connect interface.

# 🎚 Method 3 — PulseMeeter (Voicemeeter-style interface)

This is the closest conceptual match to Voicemeeter:

* Virtual inputs
* Virtual outputs
* Routing matrix
* Volume control

Install:

```bash
sudo dnf install pulsemeter
```

(If not in repo, use GitHub release or COPR.)

# 🧠 What You Usually Want (Common Scenarios)

### 🎮 Route Game + Spotify → One virtual device → Discord

Create:

* VirtualSink
* VirtualMic (monitor of sink)
* Set Discord mic to VirtualMic
* Route apps into VirtualSink

---

### 🎥 OBS separation (game + mic separate)

Create:

* 2 null sinks
* Route each app separately
* Capture each sink monitor in OBS

---

# 🔎 Check Existing Devices

```bash
pactl list short sinks
pactl list short sources
```

---

# ⚡ Important

Because Fedora uses **PipeWire**, you do *not* need:

* PulseAudio replacement
* Kernel drivers
* External sound drivers

Virtual devices are just software nodes.
