I noticed after like a minute I start to hear audio crackling in games (Steam) . I tried different headphones, updating drivers, updating realtek hd audio manager, updating Bios, Ccleaner, set power options to high performance and tried different sample rate in sound playback. Nothing . But I did noticed when recording (Xbox windows app DVR) the crackling stops? Not sure if that info helps. any ideas how to solve this or the very least whats making it do this?
