I have a tower with front panel audio connectors that don't seem to work.Well at least I thought that was the problem,now I'm not so sure.I changed the tower for a new one and I still don't get any audio or mic from the front panel.Could it be a problem with mainboard?The pins for the front panel on the mobo are all keyed so there is no way it's being incorrectly plugged in.

Any ideas?

Perhaps within 'Sounds & Audio Devices' - Advanced, your controls for the front mic and audio ports might be muted?

All of the options are unmuted but still no sound.
The onboard sound works fine at the back of the pc.Do the front panel sound connectors use a driver to work?If so, would the driver that I have installed for the onboard sound card work with the front panel connectors?

Thanks for the speedy reply :P

At all now?

If not things are working correctly as you need jumpers on the M'Board to allow the Back Sound to work. When you unplug the Front Sound Jacks these jumpers are removed and the sound should stop all together. If it doesn't you have the wrong Header Strip in use.

Also I have yet to see any Front Sound Molded Plug. These are all single plugs that can be incorrectly fitted. Also while you are at it look at the M'Board Manual and check the Designations on the Header Strip for the correct Pin Alignment and connections as apposed to the bit you plug in. The single Plugs have what they are printed on each plug. Things like Line Out Left & Right Sides, Ground, Mic Power, Mic In and so on. Generally speaking the Molded Plugs are used for the Front USB Connections not the Sound and there should be 7 Leads involved here that plug onto a 2 Row Header Strip with somewhere around 9 Pins but one row has a Pin missing second from the End. You should also have to remove 2 or more jumpers from this header strip.

With a USB Header Strip it also has 9 Pins but with that one the Last Pin on one row is missing. You also have no jumpers on a USB Header Strip.

Actually this front panel connector is in fact keyed and can only fit one way.I've built quite a few computers with this particular case and used the FP connector but I don't recall having this problem before.I am however using a different mobo than I usually do but the connection for the FP pinout is the same.

You only have the choice of a Faulty Circuit Board i the front of the case or a Faulty M'Board.

The easy option is that the Plug is not correctly set for the socket and needs altering. If that's not it you can look at either a new case or M'Board. Ain't much else possible. So since you have changed the case that only leaves the M'Board if you are sure that the Cases are well made. :)

I don't suppose you have pulled the front cover and looked at the Circuit Board that the Jacks are solder to have you? Could be some rubbish shorting it out I suppose or it could be poorly fitted and be shorting out.

Actually I was tempted to tear the front panel off and take a look at the connection to see if it was ok but I decided to change the case all together which as you rightly suggested would point to the mobo as the problem but on further investigation I came across a forum in which a guy described the same problem and it turned out to be a driver issue.

I really hope it's not the mobo cause I'm trying to get this pc finished for a client in time for christmas.I have a couple things to try first before I give up and replace the board.
