This is not a major problem. This is a split second lose of audio. I first thought it was the source material but if I went back, it was there complete. It is literally a split second. It will occur on YouTube or watching a DVD movie. Using onboard graphics. System is not overclocked. I renewed the Realtek audio drivers by deleting and rebooting. BIOS is updated and have all the latest drivers. I am posting this to satisfy my curiosity and see what comes back. Otherwise the system is operating nicely and I am enjoying it.
