Sounds not work - MSI MS-6390 (-6390-010) Motherboard

Good day sir/ma'am, hi, If your motherboard does not produce sound, it could be any of the following:

1. Your device driver for the sound is not yet installed. locate the CD that come with your motherboard. your sound card model is realtek alc 650 as shown in this website: http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c00006230 if you cannot find the driver download it from this site: http://driverscollection.com/?file_cid=4053691085452095b98d66543d7.
2. Your volume is either in mute or i a low volume setting. Check the taskbar at the lower right side of the desktop if you see a speaker icon, right click it and set the volume level to high.
3. Your speakers is not connected to the audio port. Check the baby plug stereo speaker connector to the green audio port at the back panel of the PC, (usually pink, blue and green are side by side)
4. Your speakers are not working properly. If you have portable mp3 players, plug in your speakers to it for testing.
5. Worst come to worst if your green audio port is the defective one. you can use the blue one provided you enable 4 channel, so sound is sent to the blue port.
6. your built in sound card is bad, you can get a replacement soundcard of any brand, provided its PCI slot. or get those small USB type sound card.

Hane you install the right driver for soundcard?? if you did but noting happen, chick if the soundcard is detected by computer, if dont replace it a pci-e soundcard.
