azure audio file playback delay

I have made a web based game in JavaScript which I decided to move onto the Microsoft Azure platform seeing as I am a student, so can do this for free. However, it has multiple large audio files and as a result quickly reached the traffic limit. As a result, I moved the files to my google drive and linked to them from there. Since then, the audio is delayed by several seconds and so is out of sync with events in the browser (such as button clicks). Is this a problem based off my choice of location to hold the audio files, and if so how can I fix this? If this is something else, then what would be causing the problem?

The web app in question can be found here (but please be aware it is somewhat unstable, and only runs in Google Chrome, Safari or Opera). The project does have a log in system, but this is NOT synced with any server and is purely client-side for saving any user data (as this was just made for coursework, going all those extra miles for adding a server would not help the project).
