try installing the driver from this page, it worked for me.
Thank you! Unfortunately the file R56339.exe installed just fine but didn't fix the problem. I did find another answer and link for R142745.zip; but, the link is broken and the Dell site doesn't have information on it (much less the file)! The problem is a Dell 520 which has a Multimedia Audio driver not found.
Thanks anyway for trying.

Neither R56339.exe nor R142745.exe is the right file.
Never go to those non dell sites they seed the files deliberately with malware.
Thank you so much for the post!! Been trying to fix my no sound problem for nearly 2 and half months, finally all sotred out. I just downloaded that R97809.EXE and ran it, restarted the comp and boom all fixed! I really appreciate the effort people like you put into helping others, I registered to this site just to thank you lol. You are a LEGEND!
