	Maybe you have the audio problem caused by a windows update KB4515384 https://www.windowslatest.com/2019/09/12/windows-10-kb4515384-audio-issues/

	After few months ago, my onboard audio sound stopped working. I connected different audio devices, but the result still the same. No sound anymore when playing games or youtube!! (WIN10) Now, I have to use an external sound card that solved the problem. What?�s going on of my internal audio?? Is there any solution?
