I had reinstalled windows 10 via bootable USB and after setting up win 10, i found "No audio device is installed" error message in volume section (in taskbar). I have tried options suggested by HP virtual agent but no use. However, during boot up of windows 10 I have tested speakers via HP PC hardware diagnostic tool and found that audio test was passed successfully. But while running windows, no audio is coming. Please help.
Note :- I have updated realtek driver as suggested HP support assitant but still no change.
Thanks for response. My problem is solved. There was problem with audio driver and despite installing it online it was not working. I had to download recovery media particular to my PC product ID from HP cloud recovery tool and it worked.
