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 
 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): 
 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: 
 mkdir -p ~/.config/pipewire/pipewire-pulse.conf.d
nano ~/.config/pipewire/pipewire-pulse.conf.d/virtual-devices.conf
 
 Add: 
 context.modules = [
 { name = libpipewire-module-null-audio-sink
 args = {
 node.name = "VirtualSink"
 node.description = "VirtualSink"
 media.class = "Audio/Sink"
 }
 }
]
 
 Then restart PipeWire: 
 systemctl --user restart pipewire pipewire-pulse
 
 
 🎛 Method 2 — Use a Patchbay (Graphical Way) 
 Much easier if you don’t like CLI. 
 🔌 qpwgraph 
 qpwgraph 
 
 
 
 
 Install: 
 sudo dnf install qpwgraph
 
 Launch: 
 qpwgraph
 
 You can visually connect: 
 
 App → Virtual Sink 
 Virtual Sink → Hardware Output 
 Virtual Sink → OBS / Discord 
 
 
 🔌 Helvum (simpler UI) 
 Helvum 
 
 
 
 
 Install: 
 sudo dnf install helvum
 
 Very simple drag-and-connect interface. 
 
 🎚 Method 3 — PulseMeeter (Voicemeeter-style interface) 
 PulseMeeter 
 
 
 
 
 This is the closest conceptual match to Voicemeeter: 
 
 Virtual inputs 
 Virtual outputs 
 Routing matrix 
 Volume control 
 
 Install: 
 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 
 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. 
 
 If you tell me your exact goal (streaming? mixing mic + music? dual PC? Discord routing?), I can give you the exact commands and layout for your setup.
