No sound from my PC

My Desktop PC was working fine yesterday, but today there is no sound at all
from the speakers. I opened Device Manager and found everything normal:
there was no yellow questions marks beside the Sound item. The speaker
cables are also firmly connected to the PC.

I've ran AVG, SpyBot & Malwarebyte's Anti-Malware to scan for virus, etc,
but found none.

Please help. I have a HP-Pavilion KT393AA desktop, with 2.5 g
Intel Core2 Quad Q9300 , 3.3 g RAM, Realtek HIgh Defintion Audio, running
Vista Home Premium SP 1

What are your speaker volume settings?

Check the following:

1. The speakers are plugged in and the outlet they are plugged into is
live.

2. The physical speaker volume control is not turned down.

3. The Windows speaker volume control is not turned down, nor is it
muted.

If all the above are OK, the speakers may have physically died. Try
them on another computer to be sure.

Speaker volumes, physical and Windows Vol. Ctrl are all set at mid way, not
muted.

Plug a set of earphones into the speaker jack... do you hear sound?

Many posts lately about this same issue. You are infected with malware. Suggest
running Malwarebytes and SuperAntiSpyware along with your resident AV.

You could try reinstalling or updating the audio driver. Some Windows
Update is causing audio to stop for some reason for some people.

Check if speakers were stolen

Don't pick a fight with an old man.
If he is too old to fight, he'll just kill you.

As you suggested, I plugged a set of earphones into speaker jack, and yes,
I do hear sound BUT it is very soft. It is still very soft after I turn
up all the volume settings to Max.

I have reinstalled the Realtek Audio drivers, but the problem remains.
