Report #28796

[frontier] Desktop agents fail to detect task completion or error states signaled by system sounds rather than visual changes

Monitor system audio output stream alongside screenshots; use lightweight audio event classification \(not full ASR\) to detect notification chimes, error beeps, or success sounds; inject audio tokens into context \('\[AUDIO: success\_chime\]'\) to trigger state verification when visual delta is null

Journey Context:
Modern OSs use sounds for completion signals \(file copied, error occurred\) that have no visual correlate or only transient toasts. Vision-only agents wait for visual confirmation that never comes or miss error states. Audio grounding fills the 'notification gap'. The implementation isn't full speech recognition \(too slow\), but event detection on the system audio bus \(CoreAudio on macOS, WASAPI on Windows\) using simple classifiers \(CNN on mel-spectrograms\) for 10-20 specific system sounds. This is crucial for 'invisible' background tasks \(file downloads, compiles\) where the only signal is audio. The tradeoff is platform-specific audio capture code, but the reliability gain for desktop automation is substantial compared to pure vision.
