I have the GL702 and i have the same problems. I set the PowerMgnt to 0 and the sound went more bad. I tried everything. Updated the Bios, tested 7 realtek drivers and the common windows driver. I have still the crackling sounds. Sometimes it's scratching too. I already tested windows 8.1 and ubuntu. On ubuntu everything works fine, so the soundchip seems to be okay.
My Notebook is two weeks old now and i am getting really annoyed. I don't know what i can do. At my work there are some specialists in PC and Laptops, but in the end they don't have any ideas what to do, for better sounds.
But asus knows the problem, why do they don't care about that? And why is there no driver which will fix this. Pls give me some more tips what i can do. Thanks in advance.
