Hi, I am using a 9900k on a maximus xi extreme. Sometimes I have this popping sound on through my speakers. I have changed the output from different dacs and even experiencing this issue using my screen's built in speakers. On rare occasions, the whole system would freeze for a while then continue, with the audio being jittery, like when you rapidly pause and play a video repeatedly. I might have heard wrong but I experienced a popping sound while in the bios. I have tried the 3.5" jack, front and back panel usb and displayport(screen speakers) but the issue still exists. Uninstalled the Realtek driver as well.
I have a feeling that it might be the clock module of the motherboard that is faulty that might cause a desync in the audio with the dac but that doesn't really explain the onboard audio glitch. Does anyone have any experience with this? It had never happened on my previous MB (gigabyte master).
