I wonder if you people might know why the Realtek drivers gurgle and pop at times? Do a Google search and it is affecting people across platforms and even under the new board I am affected. Sounds like it did back in the day when your audio buffers didn't have enough buffer and you were spiking the CPU when there was only a single core. Any help for that?
If you use the old (non W10) task manager you will see a single core go over 100% and that is when the Realtek will "sparkle" (this seems to be what the Google search results calls it). I think something is wrong with Realtek's drivers for a good while now and it is not multi threaded like the video drivers are since I see a single core spike above 100% when it does its problem.
edit: Oh, a fix for the issue seems to be to uninstall Realtek HD completely and go to the Microsoft W10 drivers. Worked for me but seriously? RT has lost it I think.
