Headphone static on Inspiron 15 7000 series

Jump to solution

Faint (but noticeable) static when using headphones (or perhaps inaudible on laptop speakers).

The static doesn't get louder with increase in volume and only ceases when the volume is muted.

I've updated as well as uninstalled and reinstalled the audio drivers with no luck.

Any suggestions?

Assuming you are hearing the noise while using the Realtek audio driver. As a test install the Windows native audio driver.

1. Open the Device Manager (type devmgmt.msc in the search box and hit Enter) and right click on Realtek High Definition Audio.
2. Select to "Update Driver Software".
3. Click on "Browse my computer for driver software".
4. Click "Let me pick from a list of drivers on my computer".
5. Put a check in the box "Show compatible hardware" if not already checked.
6. In the list of devices, click "High Definition Audio".
7. Click "Next".
8. On the Update Driver Warning box, click "Yes" (install the driver).
9. Restart the laptop if prompted. If not prompted, then no need to restart.

Test the headphone jack. If no noise with the native driver then it is a software problem that might be helped with a future Realtek revision. If still getting noise with the native driver, it might be a hardware problem. I can't think of a good specific test to confirm it, but you could report the issue to tech support.

Reverse the names in steps 1 and 6 to get back the Realtek driver.

On step 6, the only device drivers listed are "Audio Endpoint" and "Generic software device".

There are screen shots of the process in this thread. If your laptop is different from that the only other way I know to install the Windows native audio driver is this:

Open the Device Manager (type devmgmt.msc in the search box and hit Enter) and expand "Sound, video and game controllers". Right click on the Realtek and select to uninstall. Put a check mark in the option to delete the files, and then ok. When you reboot, Windows will either install its native driver or another Realtek driver if there were any other versions on the hard drive. So go back to the Device Manager and check for a Realtek driver. Keep uninstalling & rebooting until Realtek no longer appears under Sound Controllers and "High Definition Audio Device" appears in its place. That will be the native driver.

My mistake. I was clicking on the "Audio inputs and outputs" tab instead of the "Sound, video and game controllers" one in the Device Manager.

The static is gone. Thanks for the help!

The static is gone.

That's  good, but it means there is a problem with the Realtek driver. At some point you might rather use the Realtek driver instead of the Windows native driver, because the native driver lacks all of the features of the Realtek driver, and the external mic jack probably will not work while using the native driver.

You might want to report this Realtek driver issue to tech support.

I'm going to test this as soon as I get home.

If it works, that would be a real relief... I wasn't able to use the jack port at all because of this noise...

To be continued...

I recieved the 14 7000 series with this same problem. The motherboard then broke so it was sent for repair. I mention the sound issue twice but they returned it to me with the same problem and said it passed all the tests (quality control, ahem) They have now replaced it with the 15 7000 series but unbelievably it has the same problem. Clearly we are  looking at a systemic problem with the series.
