Audio device driver (for Aspire 7720z)
Last answer on Jan 1, 2009 5:29:14 pm GMT nerds, on Feb 16, 2008 2:48:26 pm GMTHi,
I downgrade my Aspire 7720z laptop from Vista to XP SP2.
Then I started to install all drivers, but my audio Realtek high definition card is still not recognized by the system (even after I patch it with the kb888111xpsp2).
There is only an audio controller and in its properties box I got this message "No driver installed for this device" with a sign of misfunction in the device management console.
Pretty strange, isn't it?
More strange : I found out that it's not possible to update the drivers for this device. When I choose this option (by right clicking) nothing happen (no box, no message, nada...)
When I want to uninstall this device I got this message: "Impossible because used by system !..."
Any idea what's going wrong? Should I just reformat and intall the all stuff again?
Any help would be really appreciate

You need to install hd (high definition) audio bus driver before you can install Realtek audio driver and modem driver (at least that is what happen to my laptop 7720-6712). Here is the way I did it. You need to reload original Acer MicroSuck windows Vista back on the pc. Then use Acer back up ultillity to back up driver to a blank dvd. Then load windows xp. In that dvd, there is a file name kb888111.exe (VERY IMPORTANT,OR YOUR SOUND WILL NOT WORK) run that file, when promt, let windows XP find the dirver from MicroSuck automaticly. After that, windows will promt you for sound card and modem, tell it to look for driver from the dvd. if not, you can download from Acer website. All the drivers for windows xp are in the dvd that i burned. That worked for me, I did not have to down load any driver. All device and YES, SOUND WORKKKK.
