Acer 1410 (No Audio Devices Are Installed)

Hello,

I have an Acer Aspire One AS1410 laptop, which I upgraded to a retail version of Windows 7 Ultimate. For many months, everything worked great.

About a week ago, I installed some updates that Microsoft pushed out. After those updates finished installing, my audio device was no longer recognized by my machine. Specifically, when I try to turn on the volume, I get a message stating "No Audio Devices Are Installed." Similarly, I cannot find any audio devices through the control panel or through Start->Run->msinfo32.

I first tried downloading the latest drivers from Acer's site and installing them. That did not correct the problem (and I've tried several times). I then tried restoring the system to an earlier date when everything was fine, and that too has not solved anything.

I have read in other threads about changing some settings in the BIOS, but I will admit that I am unclear on how to do this. Any additional hypotheses/theories would be greatly appreciated.

Acer's default reply is to pay for them to send me a new OS and reinstall that. I'm less than thrilled with the idea.

Cheers,
Bryce

I apologize if my original post wasn't clear. There is no audio device that appears at all in the device manager (with or without a yellow flag).

I've tried to roll back the computer to an earlier date, but that didn't work. In other words, even though I didn't have the problem at the time I rolled the computer back to, the problem persisted after the system restore.

I have also tried many times to delete the audio driver and reinstall, all without solving the initial problem. Any other possible solutions?

I have the 11.6'' screen. I do not know what it means to "flash my BIOS." Can you explain? It sounds like a very plausible solution.

Lemur,

I tried to do that, and the BIOS indicates that it updated fine and is running the latest version. However, the problem still persists (even after again trying to reinstall the driver).

Any other hypotheses?

Thanks,
Bryce

Some things to try...

Go to Control Panel / System and select Device Manager.

Under the menu "View" select "show hidden devices".

A couple of things to look for, anything audio driver related.
And.. any device that is marked as not working properly or has no drivers installed. It probably will not be under the audio section... if there are any, uninstall them from device manager.

Next go to Control Panel / Programs and Features and UNINSTALL any and all audio drivers.

Now reboot, anything?

Aphelion,

I tried that, but no luck. Even viewing the hidden devices, there was nothing that windows showed was not working properly. I removed all audio drivers, then rebooted, but the problem is still there. I then reinstalled the latest audio driver, rebooted again, but still no luck.

Any other ideas?
