Could you build this?
No Controlling external monitor audio over HDMI/DisplayPort requires specialized low-level DDC/CI communication and undocumented CoreAudio/IOKit APIs on macOS.
What it would actually take: This requires a native Swift/Objective-C app interfacing directly with macOS IOKit, DDC/CI (Display Data Channel Command Interface), and CoreAudio HAL drivers. Developing it demands specialized knowledge of display bus protocols, hardware-specific timing quirks (M1/M2 Apple Silicon I2C differences), and Apple kernel/driver communication.
