Pro Tools Duet by Apogee drivers and setup

[barclaycon]

I recently aquired a 'Pro Tools Duet by Apogee' interface to use with my PT 12.5 system on Windows 10. I had previously been using an Avid Mbox 3 which worked very well.
I downloaded and installed the latest drivers (1.0.14). I also updated the firmware for the interface.
All worked fine on 44.1kHz, but when I opened a 48kHz session it refused to launch. I checked the Panel IO and it wouldn't let me change the setup from 44.1khz. Not until I exited ProTools completely, and then I could change the sample rate via Panel to 48kHz and then the session would open.
Is this normal behaviour ? i.e. do I have to close PT completely every time and change the sample rate to that of the session before relaunching PT and then the session will open?
I never had to do this with the MBox 3. I could open whatever session and it would simply accommodate it. Are there I/O settings that need changing?

Hi welcome to DUC.

You may have something else using the interface holding the sample rate at that value. Make sure that Windows sound and other apps are not using the interface. Pro Tools should just be able to set the sample rate it needs when you open a session, without you doing anything else.

What *exact* errors did you get when things did not launch?

You are taking some considerable risk with these interfaces and Avid no longer supporting them.
