Solved No sound on startup !!!

[Rami120]

Sometimes, when I startup my laptop, there is no sound. I don't mean the startup sound doesn't play, no sound plays after that. If I go into the sound settings in the control panel, my speakers are enabled. However, when clicking the sound slider in the volume control in the taskbar, there is no green level indicating the beep being played. If I disable the speakers in the control panel and then reenable them, the level appears when I click the slider, but still no sound is played. Running the Windows audio playback troubleshooting returns no errors.
My sound driver is conexant smartaudio hd and it's the only version to my lenovo pc for win7
Tried all possible solutions
Pls I need your help !

When that happens to me, I go into Control Panel, Devices, find the soundcard and remove it -- do not delete the drivers! -- simply remove the device. Coldboot or restart -- Windows should be able to re-establish the "sound train."
