home-lab/modules/sound/easyeffects-presets.nix
Geir Okkenhaug Jerstad 9c9dcdc196 Add comprehensive PipeWire audio configuration with noise suppression 
- Add modules/sound/pipewire.nix with full PipeWire stack
- Include RNNoise AI-powered noise suppression
- Add EasyEffects with pre-configured presets for mic and speakers
- Include multiple GUI applications (pavucontrol, helvum, qpwgraph, pwvucontrol)
- Add helper scripts: audio-setup, microphone-test, validate-audio
- Optimize for low-latency real-time audio processing
- Enable auto-start and desktop integration
- Remove duplicate PipeWire configs from hardware-co.nix and users/common.nix
- Import sound module through desktop/common.nix for all desktop machines
