    Hello.

    Since clean install of windows I have notice a popping sound coming from the speaker from below.

    I have also disabled power management feature in sound manager as that is a known cause to cause the popping sound, but still does nothing.

    There was an issue with the XPS 15 L501x aswell.

    Does anyone else have this issue or know how to solve it?

    Thanks.

    If its a continuous popping/hissing sound coming from one of the speakers, then yes, I know exactly what you're talking about. I had a Dell tech come and replace the speakers, and the hissing/popping persisted, so I'm guessing it's a motherboard problem.

    My XPS L502x will be traveling back home to Dell this evening, to be exact. I'd rather not deal with this sort of crap.

    After I reinstalled my Dell XPS 15 (L502X) laptop with stock Windows 7 the cracking/popping sounds started.

    Yesterday I traced it down to the DPC Latency issue with DPC Latency Checker software ( http://www.thesycon.de/deu/latency_check.shtml).

    I followed the instructions to disable devices in the Device Manager but nothing seemed to help.. while I was connected to the Internet.

    Then it downed on me that my 3G USB modem could be the problem. At about the same time that I reinstalled my laptop, I started to use it on the USB 2.0 / eSATA port that usually faces the nearest cell tower.

    Down and below I confirmed that Windows 7 would NOT generate any noises when I was not connected to the Internet. I even tried different versions of the Realtek High-def Audito drivers thinking it was some special version that Dell had shipped from factory but it didn't help.

    I was happy that I traced the problem but it was still there. Today I decided to try using the 3G USB modem on the other USB 3.0 ports and it worked! There are no more noises.

    So my advice is: try to track down which device is causing the audio driver to get delays. In my case it was the mix of USB 2.0 / eSATA port with the cheap ZTE's 3G USB modem that I use to connect to my provider.
