Hi everyone. I have an HP Envy Laptop running Windows 8.1, 64 bit. I think this is the root of the problem - if I use Windows Live to play/splice a video the sound becomes nothing but a crackling noise. It stays that way nonstop even if nothing is playing unless I restart the computer or mute it obviously. It seemed to only be doing it when I imported mkv files, but right now it did it again with mp4. In my device manager it says for sound: IDT High Definition Audio CODEC and Intel Display Audio. I think it's also "beats audio" or something. Please help, thanks!
