Friends, I have recently updated the Realtek driver. I did this from the motherboard manufacturer's website. After completing the update when I checked the HD Audio manager then I found it non-functional to a great extends. If I plug in any speaker or headphone to it then it recognizes that properly but I am not able to change any options after that. I am also not able to select the type of the speaker setup from the speakers tab. I cannot get the volume from the speakers and when I checked the Sounds from the Control panel then it says me that speakers are plugged in.
