Ii have compaq presario c785tu pc sound and audio not working . control panel shows no audio device . in device manager other device is marked question mark . pls help pls help

make sure that your mic input is not muted. look under control panel/sound and audio devices, then under your microphone, select "volume" and make sure the input is selected (with a chack mark in the box under the mic volume control) and not muted.

go to control panel and find the device manager, you can also get thier by clicking the my computer icon and selecting manage, once their find the audio device drivers and uninstall them, then reboot, it will reinstall automaticly and you should be on your way, if not try opening the audio preferences from the control panel, goign to devices and the n selecting one or the other as the output

You will find the correct drivers by browsing to Compaq's home page and submitting the model number of your Compaq
