Inspiron 15 7000 (7559) Audio Faint High Pitch Buzz Noise



I received my Inspiron 15 7000 (7559) gaming edition yesterday. Brand new from Dell.ca, with 4k touch screen and dual HDD & SSD.


There is a faint, but noticeable and annoying high-pitch buzzing sound coming from near the center of the keyboard. This happens as soon as I use any audio after I boot. 

When I mute my speakers, the high-pitch stops and is replaced by a much less noticeable low-pitch buzz. 

The high-pitch buzzing volume is the same, regardless if my volume is at 2 or 100. 

Headphones plugged in, there is no buzzing from the earbuds, but still a low-pitch buzz from the laptop.

It sounds like as if the speakers were turned up all the way so there's high- or low- pitched static.

Edit: I'm unsure if it still buzzes when video/music is playing.


I am considering re-installing the audio driver, and I will also call support in the coming days.

I appreciate all suggestions and input!

Hello. When that model first came out, there were a bunch of posts from owners, reporting noise issues, but it was a different noise than yours. It was a high pitched staticy pop. This is the main thread about it:


You can test the audio driver by switching between the Realtek and the Windows native driver.

To test the driver, switch between the Realtek audio driver and the Windows native audio driver.

1. Open the Device Manager (find it in the Control Panel, or type devmgmt.msc into the search box).
2. Expand the "Sound, video & game controllers" and right click on "Realtek High Definition Audio".
3. Select to "Update Driver Software".
4. Click on "Browse my computer for driver software".
5. Click "Let me pick from a list of drivers on my computer".
6. Put a check in the box "Show compatible hardware" if not already checked.
7. In the list of devices, click "High Definition Audio" (the native driver).
8. Click "Next".
9. On the Update Driver Warning box, click "Yes" (install the driver).
10. Restart the laptop if prompted. If not prompted, sometimes you have to restart, sometimes not.
[To get back to the Realtek driver, do it again but reverse the names in steps 2 and 7.]

If you only have the symptoms with one of the drivers, then the other is at fault. If you have the same symptoms with both audio drivers, then it is very probably not a driver issue.

I have purchased the laptop recently, and even I have noticed that issue. Did it get resolved on your laptop? If it did can you tell me how?

I did not resolve the issue.

I returned the laptop within 30 days of the invoice and got myself an XPS.
