According the dell drivers page there are two audio codec for your device cirrus logic and Realtek. To know which codec your device is using you need to enter bios mode and look Cirrus or Realtek although providing the direct driver link for you laptop of both Realtek and cirrus.

Caution

Both drivers won’t work so find the Audio codec your motherboard supports. 

Dell Inspiron 3520 G9 driver page 

https://www.dell.com/support/product-details/en-us/product/inspiron-15-3520-laptop/drivers

here you could find the driver for your device entering the service code might give appropriate drivers but it doesn’t work most of time for audio. After installing give a restart. Hope it fixes the issue. 

I apologize if I was late in replying to you. I will go to the BIOS settings. I will let you know what's out there.

Although I wish you would put a picture of the Bios. So I know where the sound is But it doesn't matter 

Although I was hoping that you would put two links to the first definition Realtek and another link to the Cirrus 

But not a problem I will check the bios . And I get back to you 

I've gone to the BIOS board. And actually . I found that the definition of sound, 

Cirrus CS8409

Please send me the download link. So that I can download it to the device please 

Please don't send me the device page. Because I'm really tired looking at the page. 

Please. Send me the audio identification link so that I do not get tired in downloading the definition to the device 

Please

See I searched for the definition. And I found it on the site . See screenshot. and the link

I don't know what's going on there.

Although the laptop is new

It looks like you've downloaded the wrong audio driver. Here's the direct link for the correct one for your lapmargin: 0;">

Cirrus Logic High Definition Audio Driver | Driver Details | Dell US

Many laptops using the Cirrus CS8409 audio codec seem to be affected by the same issue. My laptop is an Inspiron 3501 with Cirrus, and reinstalling the official drivers alone didn’t solve the problem.

Since your computer is new, I recommend:

• Downloading Dell SupportAssist

• Making sure your warranty is active

• Chatting with Dell support to let them know about the issue

They might be able to provide a fix or escalate it further.

Here is the same I am facing restarting works for me and then again it vanishes. 

Bless you. I know you're trying to help me. And I appreciate you very much

Anyway . I have omitted the first definition. And I'm going to try the definition you sent me.

I will get back to you. To let you know the result
