But few months ago, after a windows update my audio started not working. It raises "No audio device is installed" error. I have tried several times updating uninstalling and reinstalling audio drivers but got no outcome. Some times, while reinstalling It raises, "RTKVHD64.sys" error. I was completely fail to restore audio back. Without having any other options, I reset my pc. Then, it works. Unfortunately, it didn't last long. One day again my pc lost its audio again!! I reset my again, it works for a little but after a period of time same thing happens. I need complete solution for fixing this audio issue.

@Kapil Arya - thank you for tips to restore audio functionality on windows 11. I have experienced the same problem. Unfortunately, the steps you suggested have not resolved the issue and my audio is still not working and comes up with the message 'No audio device is installed'.
On following the steps suggested, I've the following messages displayed.
This is quite different from the report in our video instruction.
Also, on accessing 'view detailed information', I get a different message to the one described in your video as follows.
My laptop is Lenovo IdeaPad 3, and have been on manufacturers troubleshooting site. Both their hardware and software have come through as working and have been updated. It seems to be clearly a Microsoft Windows problem.
I hope you can assist further.
Thanks.
