# Audio - Bazzite Audio Configuration ## Overview Bazzite uses PipeWire for audio. This skill covers virtual audio channels, surround sound emulation, Bluetooth audio, and PipeWire management. ## Quick Reference | Command | Description | |---------|-------------| | `ujust setup-virtual-channels` | Create Game/Voice/Browser/Music sinks | | `ujust setup-virtual-surround` | Setup 7.1 surround for headphones | | `ujust toggle-bt-mic` | Toggle Bluetooth headset profile fix | | `ujust restart-pipewire` | Restart PipeWire service | ## Virtual Audio Channels ### Setup Virtual Channels ```bash # Create virtual audio sinks ujust setup-virtual-channels ``` **Creates sinks:** - **Game** - Game audio - **Voice** - Discord, voice chat - **Browser** - Web browser audio - **Music** - Music players **Use case:** Route different apps to different channels for: - Separate volume control - Stream audio isolation - Recording specific sources ### Using Virtual Channels After setup, select sinks in PipeWire/PulseAudio-compatible apps: 1. Open app settings 2. Select output device 3. Choose Game/Voice/Browser/Music In `pavucontrol`: 1. Go to "Playback" tab 2. Click app dropdown 3. Select virtual sink ## Surround Sound ### Virtual 7.1 Surround ```bash # Setup 7.1 surround for headphones ujust setup-virtual-surround ``` Creates a virtual 7.1 surround sink that: - Takes stereo headphone output - Uses HRTF spatializer - Simulates surround positioning **Best for:** - Gaming with positional audio - Movies with surround tracks - Stereo headphones ## Bluetooth Audio ### Toggle BT Mic Fix ```bash # Toggle Bluetooth headset profile mitigation ujust toggle-bt-mic ``` Fixes issues with Bluetooth headsets switching profiles when: - Mic is enabled/disabled - Switching between A2DP and HSP/HFP - Audio quality drops unexpectedly ## PipeWire Management ### Restart PipeWire ```bash # Restart PipeWire and related services ujust restart-pipewire ``` Restarts: - pipewire - pipewire-pulse - wireplumber Use when: - Audio stops working - Bluetooth audio issues - After configuration changes ## Common Workflows ### Streaming Setup ```bash # Create virtual channels ujust setup-virtual-channels # In OBS: # - Capture "Game" sink for game audio # - Capture "Voice" sink for Discord # - Exclude browser/music from stream ``` ### Gaming Audio ```bash # Enable 7.1 surround for headphones ujust setup-virtual-surround # In game settings: # - Select 7.1 surround output # - Enable spatial audio ``` ### Bluetooth Troubleshooting ```bash # If BT audio drops or switches profiles ujust toggle-bt-mic # Restart audio stack ujust restart-pipewire ``` ## Advanced Configuration ### PipeWire Config Location ``` ~/.config/pipewire/ ~/.config/wireplumber/ ``` ### Check Audio Devices ```bash # List sinks pactl list sinks short # List sources pactl list sources short # PipeWire info pw-cli info ``` ### Volume Control ```bash # GUI volume control pavucontrol # CLI volume control pactl set-sink-volume @DEFAULT_SINK@ 50% ``` ## Troubleshooting ### No Audio **Check PipeWire status:** ```bash systemctl --user status pipewire systemctl --user status pipewire-pulse ``` **Restart:** ```bash ujust restart-pipewire ``` ### Virtual Channels Not Showing **Verify sinks:** ```bash pactl list sinks short | grep -E "Game|Voice|Browser|Music" ``` **Recreate:** ```bash ujust setup-virtual-channels ``` ### Bluetooth Audio Choppy **Check codec:** ```bash pactl list cards | grep -A10 "bluez" ``` **Switch to SBC-XQ or AAC if available:** Use `pavucontrol` > Configuration tab ### Surround Not Working **Check sink:** ```bash pactl list sinks short | grep surround ``` **Verify game audio settings:** - Game must output 5.1/7.1 - Virtual sink must be selected ## Cross-References - **bazzite:gaming** - Gaming audio setup - **bazzite:network** - Bluetooth considerations - **bazzite-ai:configure** - Service configuration ## When to Use This Skill Use when the user asks about: - "audio channels", "virtual sinks", "separate audio" - "surround sound", "7.1 headphones", "spatial audio" - "Bluetooth mic", "BT audio", "headset profile" - "restart audio", "PipeWire restart", "audio not working" - "Game audio", "Voice chat audio", "streaming audio" - "audio routing", "OBS audio", "Discord audio"
