Hi everyone,
I'm currently customizing my PipeWire audio setup on Solus and would greatly appreciate any feedback, suggestions, or corrections you might have. I've placed the following files under ~/.config/pipewire/ and I'm hoping for a quick review from those more experienced.

🙏 What I’m Asking:
If anyone has time, I’d really appreciate it if you could:
- Review the config files for any issues or conflicts,
- Recommend improvements for performance or compatibility,
- Or share general best practices for tuning PipeWire (especially for PulseAudio clients and low-latency audio work).
Thanks in advance for your help! 🙌
