The sing of sound with red x and said no audio

Check your Volume and make sure you do not have it on mute. If you installed the drivers then the volume must be muted. Right Click on the megaphone at the bottom right near the time and open the volume controls. Make sure there is nothing muted.

You can also get to the sound and audio volume controls by clicking Start/Control Panel and look for Audio or Sound.

If you believe that your unit has a sound card, then you simply install the drivers for the sound card. Otherwise you need to install a sound card.

Go to device manager and look for sound card

Try to reinstall audio driver on to ur laptop..

The sound device is software usually located on the mother bord install disk. else see what kind of sound the board takes and got to their , for instance realtec, sound company, web site and download the audio device and the driver , if you don't have the MB CD.

check the device manager and make sure the the audio device is detected. you need to know who the manufacturer of the sound card so you can download the driver and install it.

go to .......my pc>> properties >>hardware>> device manager >> sounds
See if the sound drivers are installed to your pc.

Go also start >> control panel >> Sounds
See if the audio is available

I guess your output is leaking and you are recording it again to the track.
Try recording with lower output volume. :)
