Hi, Yesterday the power was cut off and my pc turned off. after that my pc is not sending audio in any audio device nor taking input of microphone. I have checked the port issue by running hp UEFI diagnostics and it seems that the port is ok and the headphones are also working fine on other devices. its just that the pc is not able to send audio to any device. I have also tried connecting a bluetooth device then connected my earbuds with it but it didn't send any audio to even a bluetooth device. I have reinstalled my drivers and checked out all the possible methods I could find on internet but nothing solved the issue. Is this something related to operating system now? Would be very thankful to the community for helping me out on this issue.
