Now out of the blue today, I noticed that my audio would start buzzing/stuttering out randomly. I downloaded and ran LatencyMon and discovered that the two culprits seem to be storport.sys and HDAudBus.sys. As a result, I attempted to reinstall all of my motherboard's (Asus M5A97 R2.0) drivers but it didn't seem to fix the issue. I've also tried several system restores as well as disabling all power saving features in my bios and Windows. I'm really not sure what to attempt at this point other than a clean install. Any advice is appreciated.
