Hey there! @Rajkeshdutta, Thanks for stopping by HP forums!
I understand that you Dolby advanced audio is not working on your laptop.
Don't worry I will try to help you out.
Please try updating the IDT driver and check if that helps.
Download the audio driver using this link.
Also, Please update the BIOS using this link.
Let me know if this works!
