M5-583P and Win 8.1 upgrade issues

I recently upgraded my M5-583P to Win 8.1 and am having issues with a few things:

 

1) In my device manager, I now have an "Unknown Device" under "Other devices".  I've installed all the Win 8.1 drivers available on the acer website but it still didn't fix it.  Everything seems to be working and I don't see any obvious hardware missing from the list that could help determine what it is.

 

2) I no longer have the "Dolby Digital" applet in the notificaion area.  I uninstalled the audio drivers and re-installed them and still nothing.  I noticed there were a few different in subfolders of the audio drivers that had "DolbyAdvancedAudio" and "DolbyHomeTheater" programs as well as "DolbyDigitalPlusAA" and "DolbyDigitalPlusHT" but have no idea which one(s) are for my particular laptop.  I am rather surpirzed the audio drive didn't automatically install the correct one(s).  Any idea which should be installed?  I tried them all, but there appears to be a certain order they have to be installed in to work.

    To prove that there was a REAL BUG;

     

    The issue resolved by:

     

    disabling the mic effects from realtech controlpanel

    another thing I did : uninstall the driver (from unistall a program) then rt click on the device manager audio and point to the reatec folder and let windows auto install the driver by itself(dont belive this has a great impact ,but wish to share all what I did)

     PS:

    the Acer launch manger version on acer website "EVEN IT IS UPDATED TO 04/15/2014" the only version that worked was the one from "recovery" that is supposed to be for windows 8 !!!
