Hello everyone

I upgraded to windows 10 yesterday, and since i did my internal speakers and my headphones are not working anymore. I have a microphone called blue yeti wich can be used as an output. It's the only output that works for me. If i go to the audio output manager it's the only device i can selecet. If i unplug it i get the error:"no audio devices installed" i tried to install drivers for everything but nothing helped. i really hope someone can help me because i need my sound back(not even the internal speakers are working as i said D: )
