Reply to S4 use in clubs.

I've read some people here have used the S4 in clubs without any drop outs or problems. Currently I am running a PC and my CPU meter in the S4 software is still fluctuating and making me feel uncomfortable about audio drop outs. Although, this is the case I still have little problems with the sound, I might here a pop or crack when in browse mode but thats about it. I tried many solutions but to me it seems like a driver problem.

On that note, has anyone at all had complete audio drop outs with their S4 in a club enviroment? Not a pop or crackle but I mean complete stoppage of music where you would likely have to restart the S4 and software? This issue haunts me and it makes digital DJ's look unprofessional, so I would really like to hear from anyone if it did happen?
