Sound stopped working except system sounds

Amplifier issue. See if you are getting audio signal at audio outputs used for recording. If not, then it is NOT the audio amp and the proceeding circuits are responsible.

U might also want to check out your power supply voltages to make sure that the other components are being properly fed.

Check your sound system in options, if everything is fine its something about amplifier on digital board, you need someone to make measures

Try the speaker select switch on the front panel. you'd be surprised at how easy it is to accidentally turn it off or switch it to B speakers.

there is no unlock, safe mode allows you to correct the problem.

replaced main board

Try rebooting and hitting the F8 repeatedly as soon as the boot sequence starts. When it comes up to an options screen select repair. From there you can let windows try to repair or select to install to the factory settings.

Alright, so wait, explain that again, It stops working when your using it, or when it goes into standby?

It starts working again after what? When you come out of standby?

When going into standby, the system goes on low power may cut the power to your speakers.

Check your Power settings.

RIGHT CLICK on DESKTOP> Select properties, Go to screen saver Tab and click on the Power button, then check all the power options such as when it goes into standby, how long till it does and adjust them to your preferences, also make sure Hibernation is turned off as well, when it goes into Hubernation, it cuts almost everything.

Give this a try and let me know,
good luck

I have the same problem. All of a sudden no sound through my TV connection (but through the DVD connection the sound was still working). I changed the connection from video 1 to video 2 and got the sound back. It is not a real solution, but a practical one :-)

Does the icon come up in the tray if so check
to see if it is not muted

Go into device manager/propersties and see if
it lists any problem,if it says everything is working
properly remove it and let it check for changes in
device manger when it reisstalls see if that works

Are you getting error messages? Running in thru LINE? Is not on mute? The possiblity of both not playing would lead to process of elimination.

Keep me posted.
