Problems with Microphones, Vista and Dell Computers
I’m posting a solution to a problem I had with my Inspiron 6400, but I imagine it is applicable to any recent Dell laptop with Vista and Sigmatel audio. When you plug in your microphone Vista detects it and asks you whether you just plugged in a microphone. If you answer yes all is well. But if you ever click the box "don’t ask me again" then the prompt doesn’t come up and it doesn’t work anymore.
You can go in the control panel in the Sigmatel settings and adjust click the box "allow reconfiguration pop ups" but that doesn’t necessarily bring the pop ups back. From what I read in the forums this does fix it for some people but it didn’t for me.
I did that, and then I uninstalled the drivers for the Sigmatel device. The system will prompt you to delete the drivers. Don’t do that. Just uninstall and reboot. Vista will reinstall the drivers. Next time you plug in your mic it would prompt you again.
The only two issues I’ve had with Vista are this and how slow the equivalent of "My Computer" is when I have mapped drives for Networks I’m not currently sitting on. Seeing as how I have mapped drives for 3 different networks on my laptop it can take a long time. I stopped using mapped drives where possible and use short cuts to the network share instead.
