Default Any ideas on this (audio clock error)


I'm currently working on a number of tracks which means I'm closing and opening sessions fairly regularly. For the last several weeks I've been having a recurring problem. Often (maybe once in every 3 attempts) I get an error message when a session finishes loading and I press play.

- Problem detected with audio clock. Check that your clock source and sample rate are correct.

I have checked and everything is correct (clock is set to internal as always). If I go to hardware settings and change something like buffer settings, I get:

-Pro Tools is unable to reacquire the hardware because it is in use by another application. Please quit other applications and hit OK to retry. If the hardware cannot be acquired, please quit and relaunch Pro Tools.

When I press OK, I get:

-Pro Tools hardware is either not installed or used by another program.


-Pro Tools experienced an unknown error and must now exit. Would you like to save the session before Pro Tools exits?

Pro Tools then closes.

I have tried a couple of interfaces (Mbox 2 Mini & Mbox 2 Pro) with exactly the same results. When I use PT I have nothing else running (in the dock) and wifi is disabled. Everything else seems to work and if a track gets past the first press of the play button it seems to work as it should until another session is loaded.

This started with PT10.0 and has continued since 10.0.1 although when I first started using PT10 (the day after it was released) this was not an issue. I can't remember anything changing that would coincide with this breaking.

I have reinstalled the drivers for the Mbox 2 Pro and trashed prefs etc but, apart from a full reinstall of PT, I'm not sure how to proceed. Is there a background process that can take over your audio interface?

Any ideas would be gratefully accepted.
