If you want advice from the forum's laptop audio experts, you need to supply the model name. Or you could send a private message to the Dell guy, who may or may not have expertise in this area.

Hi lijo,

Is there any bang in device manager?

Update the audio driver from the Dell support website by selecting the operating system?

Does the sound comes when headset is connected?

Run the diagnostics by pressing F12 during startup.

Also, please click my DELL-username and write me a private message with the service tag and your Name for case records.
