During real-time playback, the audio cuts out for about 3 seconds. My current (agonizing) workaround is stopping and restart playback. Any advice is appreciated.

UPDATE 4: SOLUTION

Thanks to GammaScorpii I've learned that that the source of the problem is that the HDD housing the source media isn't fast enough to spit out the audio of footage shot with a high quality lossless codec like ProRes 422 in real-time. The problem is solved when I house some of the footage on my fastest SSD, but the drive itself isn't large enough to house all of the footage. Another solution would probably be to make proxies.

For any others facing the same issue, here I the steps I recommend you take based on my research:

Delete media cache
Render audio w/ video
Increase (or decrease) audio buffer size in the Audio Hardware preferences
Check the audio sample rate in the sequence settings
Change audio output settings (MME or ASIO)
Duplicate sequences
Downgrade preview file format (I-Frame MPEG only)
Transfer project contents to a new project file
Keep project, cache, and scratch files in same hard drive location
Create DNxHD/HR, Cineform, or ProRes proxies
Check if your hard drive processing spikes w/ Task Manager
Use (multiple) fast SSDs to house source media/footage
If the source audio format and project audio format don't match, consider converting the source audio to a matching format via Audition
Round trip audio from Audition to Premiere by import the audio into Audition and then bringing it into Premiere
