Your laptop would have have a Realtek audio driver pre-installed. Assuming that driver is still installed, switch to the Windows native audio driver to test the speakers. 1. Open the Device Manager (type devmgmt.msc in the Windows 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, then no need to restart.[To get back to the Realtek driver,  do it again but reverse the names in steps 1 and 6.] If the speakers crackle even with the native driver then it could well be hardware failure. Contact tech support to have it repaired.
I have a brand new Inspiron 11 3000 series and there is a crackling noise coming from the speakers. How can I fix this?
