Under Audio inputs and outputs, I have: Speakers/Headphones (Realtek High Definition Audio)
Under Sound, video and game controllers, I have: Intel(R) Display Audio; NVIDIA High Definition Audio; NVIDIA Virtual Audio Device; Realtek High Definition Audio.
When I pause a video for a few seconds and then resume it, the video starts with the volume much higher than it was prior to being paused.
I have uninstalled the audio drivers and rebooted but that didn't help. I have tried to update the audio drivers, but that didn't help.
OP, don't thank us yet. We haven't solved the problem. There is a chance you might have to format, but we'll exhaust every other method before resorting to that. Is anything touched between the pausing and unpausing of the video? Does it happen with all videos? What media player are you using? Does this problem occur when using other media players?
