B50-30 - Dolby Digital Plus equaliser not working after reinstalling Windows

My Lenovo B50-30 Touch notebook came preinstalled with win 8.1 Core OS.


Support page for this model is here:


Due to an irrecoverable boot failure, I was forced to reinstall the OS & drivers.


The Realtek Audio Driver version used by me for reinstallation was present in partition D at the time of purchase.


For some reason, the equaliser for Dolby Digital Plus Advanced Audio is not working like before (screenshot at the bottom).


The controls are not staying at the positions set by me & keep resetting to the minimum always.


I have carefully followed the instructions posted in some forum threads regarding this issue, but none of them helped me in solving this problem.


I bought this notebook expressly for the powerful top-firing speakers along with the Dolby Digital Plus Advanced Audio equaliser.


Please help me restore the functionality of the equaliser for Dolby Digital Plus Advanced Audio.


Any help in this regard would be greatly appreciated.


Thanking you in advance.
