my laptop voice is lost. the WIN7 OS, it shows me no audio output device.
i installed a mydrivers, but it is useless.
who can tell me how to slove the problem except reinstall the system?
Thanks in advance!
If his system is "not showing any audio device" then there will be no volume (little speaker) icon on the task bar.
Did the laptop have audio at one time? If it did, what did you do that made it stop? Can you go to "system restore" and roll-back to a time when it did work? Not sure what you mean by "mydriver", is that the driver disk that came with the laptop?
You can try to go to the "device manager", right-click on computer name at the top of the list, and select "scan for hardware changes", to see if the audio device is detected and installed/enabled again. Look for "sound, video, and game controllers" in the hardware list, and be sure it's not disabled.
I've had to reboot to re-establish my audio when everything looked like it was working. But if the system finds no driver, then there is a setting that you must clear before it will again look for the audio.
I came across this problem when I had to replace a burned out processor on the mother board. Since the replacement processor was different, Windows had to go through a bunch of "plug and play" routines where it re-connected to all of the software routine. Then it gave me a specific error on the audio driver which I searched on the internet to find the fix. It was a specific error code that turned to be nothing more than a setting error which I could correct and then reboot. I'm at a loss to remember the specific error code or setting, but it amounted to a default Microsoft device being given priority over the actual audio hardware that existed on my mother board. It was fairly deep in the "properties" of the sound device section of control panel, but you will probably get better information if you search the specific error code. I use Google for most of my searches. Great resource!
Good luck! Let us know what you find.
