    Problems with my Sigmatel Audo drivers


    Okay I have an inspiron 1721 with Win 7 Ultimate installed on it. Everything works fairly well on it except I have no audio. It says no device installed, and I have tried all types of different versions, under compatibility mode, admin, and ect... when I try to install the drivers it says things along the line of "Device object not present, quite and restart system and try again."

    I only had sounds once, and it was pure crazy loud static.


    I am just lost.....

    Update STILL TROUBLE: Audio drivers installed. I uninstalled what I found and it re-installed and did the same weird noise issues. Then when I rebooted, it shows no audio output device installed.

    Just an idea - have you tried to go into Device Manager (Windows-Break for a shortcut) and tried to remove any drivers found under 'Sound Video and Game Controllers'? And then let Windows 7 find the appropriate driver for sound.

    Reading your post again I realize no drivers were detected did you use the Vista-specific drivers for your version of Windows 7 (32 or 64-bit)? Perhaps go to Microsoft Update Catalog and proceed from there?

    There are no official drivers, BUT I did get some of the vista 64 bit to install.. After the install it shows the sound card, but with a yellow exclamation mark, and asked to restart pc. when I did, it was no longer there after restart... Did this many times...
