Hi guys, I am facing a sound problem in my Asus G50V laptop. The thing is that I have no sound after booting or restarting OS, but when I hibernate laptop and wake it up again, the sound shows up. Also, when the laptop has been shut down improperly (holding power button for a few seconds), then after booting the sound is present. So looks like shutting the system down has something to do with this issue. Does anybody have an idea what could be the solution here? I am using Windows 7 Ultimate x64, just installed it, but there was no sound in previous Win7 as well. I have installed newest audio drivers from Realtek and NVIDIA websites, and now in device manager I have two audio controllers: Realtek High Definition Audio v220.127.116.1157 NVIDIA High Definition Audio v18.104.22.168 Thank you for your advices.
