The most common cause of error 9416 is intensive Elastic Audio processing.
While AAE errors are common, error 9416 is particularly frustrating because it often appears randomly—during play, record, or even idle editing. The good news is that recent updates from Avid have shifted the diagnostic landscape. The "old" fixes from 2022 no longer work.

Pro Tools requires fast read and write speeds to manage multi-track audio sessions smoothly.
The following solutions are ranked from most effective to least intrusive. It is recommended to and combine multiple approaches if necessary.
If your session files, OS, and sample libraries are all fighting for space on your primary C: or Macintosh HD drive, bottlenecks are inevitable.
Insufficient CPU, RAM, or slow disk read/write speeds can trigger the engine to fail.
Ignore the “buffer underflow” text for a moment. In practice, 9416 is . The software asks for audio data from the interface buffer, but the buffer isn’t ready or is corrupted.
If you are importing audio from SoundMiner or other libraries, ensure the audio files are converted to your session's sample rate and format before bringing them in.
