- Device manager reports all's well but when I open Sounds and Audio Devices from Control Panel everything's a gloomy shade of grey. I try to troubleshoot but it fails to open and Help and Support has disappeared too. - gregrankin2

- I'm running a Crystal 4205 on a Dell C840. I've checked the device which is working properly. The message says the device works but is not started.

How do I start the Crystal 4205

- like i said previously i still cannot hear sounds coming from my laptop it is totally frustrating, and if there's anyone with ideas for this problem, pls feel free to post it up for me.My sound shuts off within 15mins of loading windows and will turn back on only if on standby mode, i have no idea why, and when it turn back on it'll only stay on for approx.5more mins and shut off again.I have done everything, checked device manager for yellow exclamation mark next to device and troubleshooted, still no luck, i have reinstalled new drivers for my sound device, still no resolution, i have done everything i can think of, pls anyone out there with a solution that i have not tried as yet, i am open to anything at this point, pls help.Thanks.
