I cant hear a sound from my laptop - HP (400745-001) Sound Card

Check if the sound is muted. You can also check the driver if it is outdated. You can use RadarSync to check. You just press on scan and it will do the thing for you. The scan is free but the update (automatic) needs you to subscribe for a minimal fee.

Go to your manufacturer website and select what type of model of your laptop and select your operating system then download the appropriate drivers for your audio device

do you hear sound when the headphones are unplugged from laptop?

You can download drivers from the Sony WEB site.
Select your model notebook and the Windows XP or Vista drivers you require. Use this link.

There is a volume control knob on the notebook itself.....sheck to see if this is not set to minimum...


keep me posted

Hi,
Your sound driver is corrupted or removed from your system.Try to re-install your sound driver and then try.
also scan your system with some antivirus.


Thanks

That is because you need to reinstall audio drivers, download and install from link below,

Compaq Presario 700 Notebook PC series - Download drivers

Uploaded them from what source? What is the extension on the video, and what is your default media player?

You have just about answered your own problem. If you can hear sound on other computers and also on TV, then the camera is sending out sound. You should be downloading the video to your laptop with a USB cable. Make sure that you use the same cable on your laptop that you used to download on other computers. In the worst case you could get a card reader with USB and remove your memory chip from the camera and load it into the Card reader. That should solve the sound loss. I have also seen a laptop that would make sound when windows opened up but would not play a music CD. You might want to test your laptop with a music cd before you buy anything!

ok
u r lose your laptop sound drivr reinstall your laptop sound driver
i hope ur problem will solve
