Hi Redrose, I stated my problem some comments ago, i'll just paste it so you can see if there is something else to try besides attacksofzaq suggestion:
"I'm having a weird sound issue: whenever i use a program that uses sound, if i then open another one the sound of the second one won't come out. I mean, if im listening to music and open a game, the game won't have sound. I tried reinstalling the drivers and downloading the new version and still have the same problem, its quite annoying. What can i do to fix it? I have G7 2325dx with windows 8 64 bits."
Thanks for helping me out!
