In your devices manager did you tried to update the driver on the yellow pointed one (search drivers on my computer, not online)?

NoN : i tried that too and i got this message : "The best driver softwre for your device is already installed . Windows has determined the driver software for your device is up to date"
Still the yellow (!) still on High Definition Audio Controller

Uninstall the sound in the Device Manager then restart the PC and when Windows starts it should detect and reinstall it. Sometimes this fixes problems such as this.

In the Device Manager, RIGHT click on the entry for the sound to highlight it and then LEFT click Uninstall. DO NOT check the box to uninstall the drivers. Restart the PC.

If you have kept the folder where were extracted the files...you can aswell update the same manner but choose files on my computer folder! see if its works..

Don't totally trust that the "best driver software for your device is already installed". I ran into that issue with my Dell 170L desktop video driver. Windows update gave me a new driver and I could not get past standard VGA. Rolled Back to original driver (installed in compatibility mode) and got my 1280x1024 back.
Manually install the correct driver if need be from mfg. website
Thanks worked for me with Win 7

Did the speaker work before? Maybe a defective speaker.

i still can hear the beep, but not window sound.

Is your system under warranty?
If it is relatively new I would take it back and have it fixed. While you are there check out one that is like yours to hear how it is suppose to sound. IMO

As suggested by fireberd....did you uninstall all the high definition audio from "program & features", rebooted and see in devices manager what' it says? Try reinstall the HDA software from your Mfg after that. (i suppose you went through that aswell)
