Windows 7 On Dell D610 – No Sound Driver for SigmaTelSocialTwist Tell-a-Friend

After installing the Windows 7 RTM on Dell D610, I found sound does not work and the speaker icon in task bar shows a red x.

After searching in internet I found that D610 has SigmaTel STAC 975X AC97 and I need “SigmaTel STAC 975X AC97 Sound driver for DELL Laptops”. I also find that even SigmaTel STAC 975X AC97 Sound driver for Windows XP will work.

So based on suggestion in this post “SigmaTel STAC 975X AC97 Sound driver for DELL Laptops” I downloaded the driver from ftp://ftp.dell.com/audio/R99254.EXE and installed it on my Dell D610. It creates a directory in C:\dell\drivers and install the required drivers.

After that you will have to go to Computer->Properties->Manage and select Device Manager. It will show a list of devices. You will find Multimedia Audio Controller with an error sign.
