Question about Asrock M266A Motherboard
Open the Control Panel, then System, click on Hardware, then Device Manager.
Scan down the list and open (click on the + if not already open) the Sound, Video and Game Controllers. You should see a number of generic terms and at least one that is obviously a company name. There may be an 'X' next to it indicating that it isn't functional.
Regardless whether it is marked as defective or not, right click on the entry. This will bring up a short menu. Left click on Properties. If the system thinks your device is working, it will say so under the General tab and will either state that it is working or offer troubleshooting help. At this point, note the maker of the sound chip; you may need it later. If the chip (it is almost certainly on the main board) is responding, then open the Sounds and Audio devices find the maker's name under the Hardware tab, delete it and then reboot your PC.
If Windows has just cannibalized the driver and the hardware is still working, Win should 'find' a 'new device' and try to find a driver from its library. If it fails to find one, it will ask for the chip's CD. If you don't have one, you will have to go to the manufacturer's website and download a new driver. Be sure to note its name and put it where you can find it again.
Reboot again and (hopefully) Win will 'find' it again and then when asked for a driver, you can direct it to the new driver.
If it still doesn't work, the integrated sound system may be dead and replacing the motherboard is the only way to get it back since these on-board ICs cannot be practically replaced by hand.
A very complete system report can be had from the Belarc Advisor which is free and available here and can be of help to anyone trying to deal with a glitch such as the one you have:
Run it and save the report on a backup disk so it is accessible when your system is down. Having this report handy when Wintel or AMD systems are going nuts is a good place to start troubleshooting.

Look at the bottom of your monitor on the task bar, if you see an speaker icon means that sound in your unit is active.
Let's test your speaker if it's really have a sound.
1. click start
2. choose control panel
3. choose sounds and audio devices (you can see their the driver of your audio)
4. then choose sound tab
5.under program events choose asterisk
6. click the play bottom to hear the sound.
If ever you did not hear a sound means you have to installed your audio driver.

Open up your computer case. You need physical access to the motherboard to complete this procedure
Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery
CAREFULLY remove the CMOS battery, avoid touching it with your fingers, and leave it out for about 120 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration. (See Warnings)
Set the battery back into place and power on the computer
The computer should then warn you that the CMOS configuration could not be found. You can either reconfigure it yourself or restore defaults. Restoring the default configuration should be fine.
You will notice that the BIOS password has been cleared and you can boot without it. You may reset the BIOS password to something else by going into the BIOS configuration and setting a new User Password (The Supervisor Password controls access to the BIOS, NOT the computer!)
Hope this helps
