This started happening the same day I upgraded from 8.1, but it went away. Suddenly it's come back worse than it ever was. I've tried uninstalling my Realtek drivers and rebooting and I've tried changing the sample rate. No change.
This is INFURIATING. I can't listen to music, watch videos, play games without the audio stuttering and it's driving me crazy.
I didn't find the right solution from the Internet.
