If this is the RAM leak that's been mentioned before that happens in CC 2014 when scrubbing the timeline with audio, the fix is in an update that's coming within a month or so. Personally, I would like them to release it only when they're ready so that the update doesn't cause more bugs.
In the meantime, you can work in CC instead of CC 2014 to do any audio scrubbing you need to do. (You can Save As CC, if you need to get a CC 2014 project to be compatible with the previous version.) This bug should not be interfering with any your work as the issue is not present in CC. The previous version of CC is available from the CC app as shown here: Creative Cloud Help | Install, update, or uninstall apps
If this is a different issue entirely, we will need a lot more information in order to help you. FAQ: What information should I provide when ask a question?
