Rekordbox DJ Loud Buzzing Noise

Every time I use my Rekordbox DJ, the audio will stutter almost like a distortion, there is no effect being used, it happens with audio or video. Every once in a while the audio will drop and it will make this loud buzzing noise in the speaker that I have to turn off the sound, I have no other choice but to restart the application at which point the audio stop working, when I restart the application, in other to make it work I have to go to File - Preferences - Audio Tab and finally switch back and forth audio source between Line and ASIO and back again in other to make it work again. This is really frustrating because it happens at random. Can I please get some help with this problem.

- Rekordbox DJ is the only application being used
- with Rekordbox DJ I am only using about 33% memory
