Hi Stephen
Try checking that the bit rate is the same, ideally you should both be working 24bit audio. Pull down the sequence menu, select settings, and check that your audio rate is 24bit at 48hz. The AIFF from Protools should have the same settings (which you can check in your browser). If they are different, remove the audio from the sequence, change the sequence settings to match it, then put it back on – that should fix it.
Hope that works
God bless
