Alienware m17x Windows 7 HDMI Stop working - FIX SOLUTION

I went to a little bit of hell when upgraded my Dell Alienware m17x to windows 7 64 bit ultimate. It's been working great for a while but out of no ware the HDMI output stopped working. I check the HDMI cable but it was a good cable. I could not get my HDMI working to my external dell 24" monitor nor my HDTV. After digging around I went to dell.com downloaded the latest BIOS driver for A03 release on 1/11/2011. To to dell.com and get the latest windows 7 BIOS driver. http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R254103&SystemID=ALW_LP_M17X&servicetag=&os=W764&osl=en&deviceid=19197&devlib=0&typecnt=0&vercnt=4&catid=-1&impid=-1&formatcnt=0&libid=1&typeid=-1&dateid=-1&formatid=-1&fileid=372828

After updating the flash bios it started working like a charm.

Dell Inspiron 1720 Windows XP Pro Working Audio Driver SIGMATEL STAC 92XX

After wiping out Windows Vista and installing Windows XP Pro SP2 in my Dell Inspiron 1720 I found my self in trouble. I could not find any where in Dell's web site or forums the driver for the sound device for my laptop.

After several hours of search and trying different drivers I found a driver only available in Dell's German Language for the SigmaTel sound card R153908.exe.

You can download it from Dell's website here or you can get it from my online box here.
Just donwload run the file it will extract all the files to a directory default "c:\dell\drivers" and the setup will be launched.
