If its says that "no audio d3evice found " then your laptop's audio drivers are missing
try driver disk
and reinstall audio drivers(sound card driver)
and this will re install your audio driver and your laptop can recognise sound card

what u have to do is go to control panel and then go to hardware and sound. then u have to click play CD and other median automaticilly and then u have to clid DVD drive and it will then work. then exit out of control panel and go to computer click DVD player, put the DVD inside ur DVD drive. then double click the DVD icon and it should play
Have you tried using the Control Panel to see if something got changed? Navigate to the Control Panel by clicking Start, Settings, Control Panel. Then double click on the Sounds and Audio devices icon. Make sure the Mute box is unchecked and the volume is turned up.
Unplug speaker connection. Go to Control Panel, double-click on "Sounds and Audio Devices" and on "Volume" tab make sure "mute" is not checked and that volume is sufficiently up there. If thats ok select "Sounds" tab and go to "Program events", select any Windows sounds and check to see if you can hear the sound by clicking on the arrow next to it. If you can hear sound its ok so then check your speakers connection to correct sound output jack and that external speaker is powered on.
I had this problem too. My built in mic wasnt working, but i went to the list of programs (Classic view of the start menu) and under the program folder TOSHIBA > Speech System it'll have a choice "Configure Microphone." After I went through that, it worked fine. Make sure you restart your webcam software though after you've done that if you had it open like me. Hope this works!
