Fail to install audio driver lenovo G550

One quick thought and thing is worth a try, right click each Other Device, select Update and allow Windows to search for a driver. Perhaps it might find/fix it
 
Barrrrrrrrrr10, fyi, when answering the post just above it's not necessary to quote it.
 
I'm willing to try a little debugging (helps me learn more about windows too :) )

Windows 7 maintains a device driver install/uninstall trace file in C:\Windows\inf\setupapi.dev.log. They're not easy to read but comparing yours against my own, maybe I can see why the controller driver install is failing.

> Delete C:\Windows\inf\setupapi.dev.log
> Reboot your machine.
> Wait awhile (a least 5 minutes - after all those driver install message bubbles stop appearing in notification bar at bottom right of your Desktop)
> Rename the trace file. Change its extension from .log to .txt so you can now upload it to TechSpot

Then I'll take a look if anything I can make sense of...

/* EDIT */
p.s. no need to quote this post when replying, as mailpup pointed out, when the dialogue is one-on-one (or unless you need to emphasize/point out something that had been said)
