I have a custom built computer that i've been using for almost 2 years now and i've never had this problem. Recently i upgraded to windows 10 (all the drivers are up to date according to device manager). The problem didn't start until a few weeks later when i downloaded some poker software. What happens is i'll restart the computer and the sound will be fine for a while. Then at some point usually within an hour or two of use the sound will start to crackle and distort at times. The weird thing is, besides it only happening after a certain period of time, there's really no logic i can see to when and how bad the sound will "fizzle" if you will. Sometimes it's fine, sometimes it's only a little bit, other time it will go crazy. As far as i know my hardware is all fine and the app in question fairly reputable and widely used. Any suggestions on what could be causing this?
