Laptop starts up with no sound

[atteh]

i have a laptop with win 7 64 bit using "ATI high definition audio device" (what is says) and my drivers are up to date as far as i know, what seems to be happening is that sometimes when i start up my computer, sound wont be present thus making anything multimedia related such as music, youtube, games anything like that will either freeze or just wont load. has anyone ever heard of this

Usually, "ATI High defintion audio device" refers the audio that is available on the HDMI output, not the PC's sound module. Go to the Control Panel/Hardware and Sound and finally the Sound panel. In the "Playback" section you should have the ATI device and also a "Speakers" icon. Select the Speakers as the Default Playback device and see if that corrects the problem.

speakers were actually what were set as default anyway

Go to the Device Manager, uninstall the sound (probably RealTek or IDT) in the Device Manager then restart the PC and when Windows starts it will detect and reinstall the sound. This fixes a lot of flakey problems and MAY take care of your sound problem.

To access the Device Manager, hold the Windows key down and press the Pause/Break key. When the Panel comes up the Device Manager can be accessed from the list in the upper left of the Panel. In the Device Manager, RIGHT click on the entry for the sound and then LEFT click "Uninstall". DO NOT also uninstall the drivers. Restart the PC.
