I have an issue where if I unpause media content, the system volume jumps to 100 without it actually "being" 100. The solution to this problem is usually to uninstall the sound drivers and then restart to force them to reinstall. When I do this, it causes my headphone jack not to work at all. Then, if I "update drivers" from device manager OR install the latest drivers from the realtek site, the problem persists. I'm kind of stuck between a rock and a hard place.
