I tried everything given in this thread, but none of them worked for me

I've attached my report from Everest tool with this thread.

Quick Info about my System:

Error: No Audio Output device is installed

Please help me in resolving this issue. Thanks in advance

 

Did you try going into device manager, right clicking on the audio device, selecting properties, then the driver tab, then the enable button?

 

It was enabled. I disabled and enabled it again. Regretfully it doesn't help my cause
