Question about MPC Computers ClientPro 414 All-In-One PC Desktop
You either have a broken volume control knob or incorrect/missing drivers. You can download the drivers for this product from a company called Mecer:
Does your volume control knob spin more than 360 degrees? It should not, and if it does, then it's broken. Here are three solutions you can try for fixing it:
#1: This is probably the easiest one to accomplish. Remove the cabledooron the back of the system (it is the one at the bottom on the back --held in by one screw). Under this door there are anywhere from 5-6cables plugged into the motherboard. One of these is a connector with30 pins arranged in two rows of 15. The cable plugged into thisconnector probably has pink wires. Short pins 7-8 on this connector(they should be across from each other, but only pins 1, 2, 29, and 30are labeled). To short the pins, insert a thin wire into the back sideof the connector so that it makes contact with the exposed pins. Youcould also use a resistor to do the trick - 10KOhms will give you novolumewhile 0Ohms will give you full volume. Something like 2.5K could giveyou a nice middle ground.
#2:Replace the volume knob. The part number for the knob isXV0107GPV2NB10K-3824. Good luck finding someone who will sell you oneof these.
#3: Disassemble the LCD panel (it's not that hard ifyou have a #1 phillips screw driver) and short the volume control knobpins 2-3. This will disable the volume control completely, but it willbe stuck on maximum volume. This would be best done by soldering a wirebetween those two pins.
Options 1 and 3 will disable the hardware volume control, but the software volume control in Windows will still work fine.

Do you see a speaker on your desktop on the lower right hand side? If you do, then click it and look to see if you have anything that is muted. If everything is fine then go to Settings and control panel and look in mutimedia. In audio, make sure your sound card is appropriately set. If you dont see a speaker or you dont see your sound card in multimedia, then you need to reinstall the drivers for your sound card. If everything checks out fine and it says your sound card is working properly...then check the speaker connection in back of you computer. Good luck.
