Premiere Pro Issue With Editing Sound inside Audition

If I try and edit a sound file in premiere pro to edit it in audition - Premiere pro seems to not let the audio run.

if I go >> "Edit Clip in Adobe Audition"

So it processes >> "Render and replace"

Then I get a warning >> "Audition has detected a problem with the current audio hardware settings".

(The hardware settings are as they always are I believe).

Currently I have to close down premier pro if I want to use audition to edit the sound file which means I have lost this functionality. 

Anyone suggestions?

Thanks
