Ok, here is the break down of the issues i've experienced with sound on my pc (Compaq Presario CQ57)
On initial install of windows 10 my sound driver was ok, after running an update and getting the latest build. My driver was no longer being recognized and i could play no sound. I was able to successfully download my manufacturer sound driver and have sound working again. I am not getting any distortion but i only played for about 10-15minutes wort of music at max volume before shutting off. Oh and it seems that my directx 3d , this occurs before and after fix. Below is the dxdiag for my machine with issues:
