So, here's the thing. When my PC had Win7, everything worked fine. I upgraded to Win10 and then suddenly I couldn't get a sound from my PC. S/PDIF was the only sound device. I use Yamaha YST-MS30 analog speakers and probably the source of the problem is the sound card (intergrated). Please help me! I also uploaded a DxDiag.txt for you guys. I believe I used to have SoundMAX but not very sure about it. If it's possible I would like a quick response. Thank you.
