I have not been able to find a solution after over a week of looking for one now. I've spoken to several HP technicians and browsed multiple forums and have tried every suggestion recommended. I get a crackling/ static sound coming from my speakers when playing audio. I have tried the laptop speakers, headphones, and 2 different external sound cards and get the same problem from all, so I have ruled out the hardware as being the problem. I have updated every single driver on my computer and even the latest BIOS and still have the problem. I've ran the driver installation files in Vista compatibility mode too. I didn't have this problem with Vista. I've also tested all the cables I've tried on another machine and they all work 100% so its not the cables either :/ Pleasse helpp me.. I have an HP Pavilion DV4-1275MX running Windows 7 Home Premium 64 bit. Thanks. UPDATE**** Ok I was able to get one of the external usb sound cards working (creative x-fi surround 5.1) without static by removing the "latest drivers" that were installed by windows update and installing it after downloading it directly from the product's support website. Now that same solution wouldnt work for anything else since I was already downloading the drivers for everything else directly from the support websites of each. I guess I'll have to do with that one alone for now. Btw the other sound cards that I have (with each of their latest updates and drivers) are the Turtle Beach Audio advantage Micro USB card and the onboard audio for the laptop itself.
