First of all I must say that not every game causes the sound to crash**
That said, I'll go ahead.
I don't know if its driver related or the motherboard that has a problem but, whenever I play Left 4 dead 2 or Heroes of Newerth for some time.. lets say like.. 20 minutes or so or when there's intensive sound happening like everyone shooting guns at the same time or something, my sound just STOP working completly. Not only the ingame sound, but every sound, even in WINDOWS. I can listen to any music or any games sound unless I reboot. And I'm bored of rebooting everytime it happens.
I tried a new realtek HD driver, I've tried desinstalling it, reinstalling without any solution.
Altho now I desinstalled the driver and I let windows find one. So instead of being Realtek High definition audio driver, its only High definition audio. It seems like working fine for now.. But I still want to know if its a problem with realtek drivers..
Thanks for helping me.
