# Pro Tools Error 9128

## Scope

Pro Tools 9128 error when running SurCode for Dolby E Decoder, w/PT 9.0.3 & 10.6.6, Magma expansion chassis

## Description

"9128. 'You're running out of CPU power. Take out some plug-ins to free up CPU power.' [299475]

"PT "gas gauge" was running at under 10% uilization but user was seeing big spikes and then it would error out. Restarted the app, completely reset his TDM hardware, no change.

Solution: In PT setting's Playback engine menu, user took one core out and increased his playback buffer. Bringing sessions in from Windows & native systems, his settings may have changed which precipitated the problem.
