I'm getting partial playback...

[Distorchestra]

I have pro tools 9, I switched the computer output to internal speakers in the preferences menu to watch and listen to a movie on my Mac Pro. When I tried to switch it back to the output, my pro tools session was only playing the bussed tracks. Oddly enough when the headphones were half way in, I could hear some of the tracks but when I plugged it all the way back in, I could just hear the bussed track. I cycled thru all of the out put options to no avail. I am new to pro tools and need to mix a session before Monday. Can anyone offer assistance?

Is the Eleven Rack set as your interface for Pro Tools?

Did you try Defaulting the IO?

I am using an eleven rack. And I did default the I/0

Can you please list your system detail in this thread so others can see them. I am a Windows guy, so since you are on a Mac, you will have a better chance of getting help if you post the details of your system here.

Are you trying to use Aggregate? Do you have the latest drivers installed? What OS? What exact version of Pro Tools? Are there any other interfaces being used?
