Suohai
Audio input/output source locking and switching tool for macOS.
What is Suohai?
Suohai is an audio input/output source locking and switching tool for macOS. It allows users to control which audio devices applications use for input and output, preventing automatic switching and providing quick manual control over audio routing.
macOS users who frequently switch between multiple audio devices or need to lock specific applications to particular audio sources.
Suohai provides a simple, native macOS solution for audio device management without the complexity of larger audio routing applications, focusing specifically on source locking and switching functionality.

Pros & Cons
Pros
As a native application with system tray accessibility, it integrates seamlessly with macOS, ensuring reliable performance and a familiar user experience, as implied by its design philosophy.
The clean, minimal UI avoids unnecessary complexity, making it easy to lock and switch audio sources quickly, which aligns with the project's minimalistic approach stated in the README.
Prevents applications from automatically switching audio devices, a core feature that addresses common frustrations in multi-device setups, as highlighted in the key features.
Enables rapid changes between connected audio input and output sources, improving workflow efficiency for users managing multiple interfaces, based on the described functionality.
Cons
Focuses only on basic locking and switching, lacking advanced features like per-application volume control or audio mixing, which limits its usefulness for professional audio workflows.
The README provides only minimal installation instructions with no troubleshooting guide or detailed usage examples, making it harder for new users to resolve issues or explore advanced options.
Being GUI-only restricts automation capabilities, as there's no mention of a CLI for scripting audio management tasks, which could be a drawback for developers or power users.
