Windows 10 update wiped my audio drivers on my HP Pavillion DV7

Apr 1, 2018
I have an HP Pavillion DV7 Notebook. A 3165DX. Has an AMD Turion M620 Processor & 4GB Ram. It had Windows 7 Home 64bit. Now upgraded to Windows 10 Hm 64. The 1st Upgrade wiped out my Beats HD Audio. Then the most recent update of 10 wiped out any and ALL HD sound drivers and left me with distorted wobbly sound which screws up my iTunes downloads when copying a CD. the Realtek software looks like it's still installed, but Microsoft techs tell me the drivers are no longer available for Realtek. Their suggestion...Buy a new updated laptop. Can anyone help me get my Beats Audio or Realtek Audio Drivers working again?
