FIX: Pro Tools could not set sample rate to specified value

After upgrading to the newly released Pro Tools 9, I couldn’t open sessions or create new ones. I got this error: “Could not complete the Open Session… command because Pro Tools could not set sample rate to specified value..” I hunted around on the web and various forums, but couldn’t find a solution that fit. I found several items relating to Windows and Pro Tools 8, but nothing for a Mac running Pro Tools 9. After messing around a bit I figured out the problem was with my playback engine. Here’s how I solved it. Let me know if it works for you too.

Open the Playback Engine dialog under the Setup menu item.

From the menu bar select Setup > Playback Engine… to open the Playback Engine dialog window.

The problem is with the Pro Tools Aggregate I/O.

By default, my current engine was set to “Pro Tools Aggregate I/O.” It’s odd that this Pro Tools would leave it that way after an installation since AVID states that it is not supported in OS X.

Select your current playback engine.

The fix is easy. Simply select the right playback engine. Your options may differ based on your setup.

In my case, I usually would edit with my Mbox 2 Micro, but since Pro Tools 9 gives us so many more options for hardware compatibility, I selected Built-in Output. I was able to edit some vocal takes using my Macbook Pro’s speakers instead of pulling out my headphones. Nice!

How to Fix a JBL EON10 G2

So your JBL’s are rattling when you pick them up, eh? Getting that uneasy feeling about that clunky noise when you move them? If it’s the same unsettling noise I heard, then I have an easy fix for you. 1. Disconnect the speaker from all power sources.* 2. Place the speaker face down and open up the shell by unscrewing all the screws around the outside edge. There’s like a million of them, so use a power drill with a long #2 phillips driver bit. 3. Lift the shell off and set it aside. Be careful not to lose any of the screws. 4. Locate the magnet coil and tighten the bolt that runs through the center.
5. Replace the shell. 6. Tighten all screws. 7. Enjoy your clunkless speakers. NOTE: I am NOT a licensed repairman, electrician, or lawyer. I have no idea if fixing this problem will void your warranty, so don’t blame me if/when JBL won’t service your speakers. Nor will I assume responsibility for you doing something stupid while dinking around with dangerous electronics. Make sure you unplug the speaker first and don’t touch anything inside. If you kill the speaker or yourself, I am not liable.
