sound effects missing for me too

Hello, I am italian, my name is Gabriele.
This forum is very useful.
Win 10 works very well but for realtek audio driver i found all here.
Thank you.

in win 10 64 bit 1903 with all drivers, (i'm using now 8694) only stereo front speakers works.
Even with checked 5.1 fill speakers, surround speakers don't work

8678 cab drivers won't install...
