No sound from my computer


I have a Compaq presario CQ50 laptop that I recently took in to have cleaned up (files cleaned up, defraged, anti virus check, etc.). When i got it back the sound did not work through the speakers but it does work through the headphone jack.

The owner said that they didn't do anything to the sound but I could check a couple of things. he confirmed:

"the software volume
controls are set correctly. The only thing I can think of is that there is a
hardware mute button on the laptop itself or some other kind of external volume
control (buttons or volume wheel) on the side or front of the laptop."

another friend said i could check the BIOS.

Can anyone help me solve this?

I wonder.

Look at the speakers selected in the control panel. Sorry but this area is NOT STANDARDIZED so you are left to go find it.

Your response - no sound issue

thanks for your response. The control panel lists 3 items. The first is "Conexant High Definition Smart Audio 221". it has a green check mark next to it saying "working". Under that is another speaker option for an Epson projector UD Audio device not checked or any symbols. Below that, the last, is a "NVIDIA HDMI Output" showing a red down arrow saying "not plugged in".

Does this tell you anything?

I've unsubscribed since we now know what to look for.

The lack of a proper document and lack of standards in this area does not help but at least you know what to look for. If you have a complaint, it is with the industry for not fixing this and with the consumers for accepting this mess.
