      Issue Summary

      Progressive audio desynchronization (audio drift) occurs from the start of recordings made with the Loom Mac Desktop App when using the default ScreenCaptureKit (SCK) pipeline.

      Steps to Reproduce

      1. Open the Loom Mac Desktop App on macOS.
      2. Start a recording with "Enable SCK capture" toggled ON in settings.
      3. Record video and audio continuously.

      Expected Results

      Audio and video tracks remain perfectly synchronized throughout the duration of the recording.

      Actual Results

      The audio track progressively drifts and desynchronizes from the video track starting from the beginning of the recording.

      Workaround

      Disable ScreenCaptureKit and use the fallback recording engine:

      1. In the Loom Mac App, navigate to Settings > Video & audio.
      2. Toggle OFF "Enable SCK capture".
      3. Toggle ON "Use fallback recorder".
      4. Relaunch the Loom app.
