"AAE Error 9416" is a common error in Avid Pro Tools. It occurs when the audio engine cannot communicate with your audio interface (sound card) or the hardware settings have become corrupted. The "updated" tag in your search suggests you may have recently updated your software or operating system, triggering the conflict.
