Missing audio (Aria T'Loak & Batarian Mercenary Recruiter - ME2)

When Shepard first lands on Omega & speaks with Aria T'Loak, the first line of audio is missing.  Aria's lips move but no audio can be heard.  This same issue also occurs when Shepard speaks with the Batarian Mercenary who's recruiting freelancers to take down Archangel on Omega.  Seriously EA, how can bugs like this exist when they weren't an issue in the original trilogy?  Does QA no longer exist?  Beyond ridiculous...
