As the tiltle says I can only hear system sounds now. But får about 5 days ago I could hear all sounds on the entire computer (games, spotify etc.), but when I started the computer yesterday i had no sound (only Windows 10 internal sounds like groove and notifications). Let me explain, for an example i have no sound when I play games or try to use spotify etc. The only sounds that work are the ones that are made by windows. I have gone into playback devices and clicked test, then I can hear the plingiding, but then when I go to RealTek's HD-soundconfiguration (not sure if properly translated from Swedish) and click test there, there is no plingiding, there is no sound at all. I can hear sounds from google chrome like youtube and videos online, but no sounds from the team application or my Steam Games. I've updated my headphones drivers (Qpad QH-90), reinstalled RealTek's drivers 2 times, looked around in the gamefiles, reinstalled DirectX 3 times, checked almost every forum, I've checked the cables from the sound input to the motherboard, I've tested other headphones and I can't find the problem! I actually seem to be the only one with this problem and haven't solved it. Please help me with this. This is my final shot.
