Hi, I bought this laptop one year ago (Samsung R519) and it's been wonderful so far. The sound volume was quite good. I've been installing and uninstalling Windows many times. I don't know if that has anything to do with the problem, but the sound volume has been gradually getting lower and lower, and now I can hardly hear the music or the videos os whatever. I reinstalled Windows 7 (32 bits Home Premium) at least twice and the problem persists. I don't know if this is a hardware or software problem, but I changed and updated the sound driver and tried many things from the software side and it doesn't get any better. So, does anyone know if this is normal in laptops to go losing volume in time (1 year)? Does anyone know what the problem could be? These are the technical specifications of this laptop: ww w. lapspecs. com/wiki/samsung+r519 Thank you very much.
