Object audio randomly pausing

I have created a music player in Captivate that has numerous buttons on a slide. Each button is linked with an advanced action to "Play Audio." The audio clips (all 30 seconds) are located in the library. When I publish the Captivate project to a web server (Blackboard and Google Drive), I can click on the buttons and the audio plays fine in its entirety for the first 5 - 10 songs. After that point, the audio pauses at completely random points during each audio clip. I have tried multiple servers and am experiencing the same issue. I've tried everything that I know how to do to get the audio to play correctly. I've also extended the length of the entire slide to 10 minutes to ensure that the files weren't getting cut off. I considered buffering being an issue, but I'm not sure how I would fix this. Please help!!!
