name: Audio Stability Fixes about: Submit changes for macOS audio recovery system title: “[AUDIO] Fix macOS audio device recovery” labels: ‘bugfix, audio’

Description

Implemented core logic for macOS audio device recovery when devices randomly stop during long sessions (>48h). Addresses silent failures in CoreAudio/ScreenCaptureKit.

Changes

• Added zombie state detection via heartbeat monitoring
• Implemented 3-stage recovery process:
  1. Soft restart (reinitialize stream)
  2. Device-level reset (CoreAudio)
  3. Full pipeline restart (fallback)
• Added recovery metrics tracking

// Key addition to AudioManager
impl AudioManager {
    pub async fn hard_reset_device(&self, device_name: &str) -> Result<()> {
        self.stop_device(device_name).await?;
        
        // macOS-specific cleanup
        #[cfg(target_os = "macos")]
        macos_audio::release_device_resources(device_name).await?;
        
        let device = parse_audio_device(device_name)?;
        self.start_device(&device).await?;
        
        info!("Hard reset completed for {}", device_name);
        Ok(())
    }
}

Notes

• Logs available via tracing subscribers
• Metrics exposed via AudioManager::recovery_stats()
