Yeahhh i had this too! I did fix it though, I believe the method of fixing is buggy af and isn't what it should be. I changed all the quality hz settings etc as well, Ripped out all the drivers for it, Re-installed to get stuck in the install loop of realteks piece of ass, Managed to fix that by turning off the net and stopping windows finding an audio driver cause the realtek one wasnt there, thus it was telling me there was one( There was cause ms kept reinstalling it auto). Once i done that, I ran my audio through boom 3d and im back, Albeit crackly all of a sudden, Thats new.
try this
1) Close out the installer.
2) Go into Control Panel, then Sound Video, and Game Controllers.
3) Right click on Realtek Audio and uninstall it yourself. Remember to check the box to delete the drivers (I didn't the first two times) or this fix won't work.
4) Reboot the computer. Don't run the installer before you reboot, or you'll be back in the same boat (like I did).
5) Now run the installer again. It will install the drivers and close out. It doesn't ask you to reboot, but it might still be a good idea. You should be good to go.
