No sound coming out my rear

[sunrise]

I just put together a new system using a MSI motherboard NF750-G55. I loaded Win7 Pro 64bit and assorted drivers. The trouble I don't get any sound when I plug in speakers from the rear, but I do get sound when I plug them in from the front. I do get the pop up window telling me I've plug the speakers in from both the front and rear plug but only sound from the front. I've tried every possible combination with the Bios and the front speaker connection. Even unplugged the front speaker connection on the motherboard and jumped pins 5&6 and 9&10 . I'm slowly coming to the conclusion that the problem is the motherboard itself. Does anyone have an idea? I'm open to all suggestions.

I don't know about you but I'm happy when there is no sound coming from my or anyone elses rear!

OK jokes aside.
It doesn't sound like a bios issue. Has this happened abruptly or is this after a windows reinstal? If not after a reinstallation did the speakers just stop working and cause you to inspect the issue? I would check the sound controls in the control panel and double check to make sure nothing was disabled. In addition if there is any special sound software on your PC I would check the settings in those too. If everything is in good order software wise I'd assume it may be a damaged port in the back if someone pushed the pc into the wall too hard. I've seen that be the cause before on devices.

Am I reading it wrong or do you have speakers in BOTH front and rear? Your sound system may be unable to handle both at the same time if that's the case.

this is a brand new motherboard right out of the box. I did a clean install on a new Hard drive Loaded the drivers and everything seemed to be good until I plugged in the speakers, it was then that I noticed the sound didn't work, so I plugged the speakers in to the front of the computer, and the sound worked. I'm thinking the rear plug is damage because I've played with with all the sound controls but no success. I'm going to do another clean install and see if maybe something happened during the first install

Ok you say you did a clean install.
Did you load the audio drivers off the cd?
This is the audio for that motherboard
• Chipset integrated by Realtek® ALC889
– Flexible 8-channel audio with jack sensing
Thats likely one of the best audio chips out there
Now if you loaded the audio drivers it would have installed a small orange speaker in the tray and when you plug something into the jack it pops open a Realtec configuration window
and would auto sense it and ask you what was plugged in.
Is this what happens?
I have yet to have to do anything with jumpers to enable front and rear sound at the same time. Merely plug the cable from the front ports onto the motherboard. There isnt any jumpers to move that I have had to move.
I would remove all jumpers you touched and then plug the cables in and load the drivers.

I finally got the sound to work using the rear jack. When I plugged in the speakers it was auto sensed by the computer and would ask me what I had plugged in. I would always tell it stereo speakers, my son suggested telling it head phone instead, which I did and what'aya know it worked. So I then unplugged and replugged this time telling it stereo speakers, no sound, unplug-replug-head phones I get sound. Explain that one to me Ferrit

What color is the jack you plug into?
Did you put back the jumpers you moved?

[sunrise]

The green one -Line out
All jumpers were removed and the front jacks connected

I would grab the Realtek drivers off the realtek site for that
and install them.
Its the HD Audio drivers

I figured it was drivers too but I went to the MSI site and down loaded their latest drivers, installed them and bud-a-bing bud-a-boom everything worked properly after that.

Persnally I would use the Realtek ones as the MSI ones are usually several revisions behind
