I have download Realtek HD Audio CODEC at least 5x only to find their is no driver component in the driver download.

Come on guys when we ask for a driver we expect to get one, not go around in circles looking for the right download group to have a driver. Is false advertising.

My Realtek sound card won't record in stereo mix! I tried everything, including downloading drivers. What's really sad is my other computer is 5 yrs. old and it runs stereo mix perfectly.

When you pay for new software, the idea is that you get useful new features but this is the exact opposite. Realtek is truly a disappointment
