Hello everyone

I upgraded to windows 10 yesterday and now i don't have any sound left. My internal labtop speakers don't get recognized and so are my headphones. i have a microphone(blue yeti) wich chan be used as a output, and it is the only one that works. I cheked the output in the device manager and the only thing i was able to see there was the microphone. If i unplut the microphone i receive the error:"no audio output installed"

I tried to install some drivers, nothing worked. My headphones don't work and neither do my labtop internal speakers. I really hope someone can help me with this problem
