Having problems with your PC Desktops ?

No sound - possible sound card hardware failure

\015 I have an ACER Aspire E650 MMX 1 desktop computer that now has no sound. This occured after the box was moved and the speakers became accidentally disconnected. I suspect that the sound card has been damaged. I have checked that it is not the speakers by swapping them to another PC. I have also checked the Sound and Audio Devices Properties for the "Realtek High Definition Audio Properties" but this says that the device is working properly. The drivers appear to be recently updated.\015\012Is there a check that I can do to confirm whether the sound card hardware is damaged ? Appreciate any advice - Many thnx & rgds - Gary\015

Dear GaryFerguson,
\015\012
\015\012The best way you can check the life of your sound hardware is to follow the procedure mentioned below.
\015\012
\015\012Since this may have happened a day or more before: To ensure if the sound card is not having any problem with the Software drivers and is purely hardware failure, Please go through this exercise:
\015\012
\015\012Roll back the setting to earlier time:

Click Start Button,
Then select All programs,
then "accessories",
then, "system tools",
then, "system restore",

A utility will start. click Next.
(Please note that it will not cause any harm to your data so dont worry about it.)

after flipping through couple of screens, it will give you an option to roll back the settings to an earlier time.
Select an earlier Bold date (that means a system check point exists) click on a check point and click next.
It will ask you to restart after reload. Allow that.
(The system will be rolled back to the point you selected (select a checkpoint that was earlier than the problem occured)).

you will see that once the system will restart, it has restored the system settings to an earlier time and your problem is resolved.
\015\012If it doesnt not resolve the problem, then you can be sure that the hardware has failed completely and needs replacement.\015\012 \015\012please comment here if you need me for something else.
Have a wonderful day.\015\012
Thanks & Best Regards,

Hi there.
Plug the speaker jack into the green audio port, also check that its not on mute.
To test the card get a pair of earphones and plug it into the pink port and see if you hear the audio.
Post back with the results please.

Good luck and thanks for using FixYa!!
