Alright, I finally got my hands on an Atrix (used). Super excited great price. I get it home and realize the audio jack doesnt work!! Well after messing around with it I find it works intermittently. If its working and I tap the phone it stops working. So I figured I probably had a bad solder or broken connection. It was actually corrosion.
To verify that your problem is in fact hardware related go to settings>sound>media audio effects. You will see 'Wired Stereo Devices' and 'Phone Speaker'. If you plug headphones into the audio jack on your atrix you should the word 'connected' immediately pop up under 'Wired Stereo Devices'. If you do not and the the word 'connected' stays under 'Phone Speaker' then you probably have this problem.
You will need to opened up your phone by removing the 8 (i think) T5 screws from the back of your phone (remove the back cover, battery, sim and sd card first!)
Then carefully separate the back plastic piece from the face of the phone. Start at the bottom where there is a little latch you need to free with a small straight blade screw driver or electronics tool. Carefully work them apart and your phone should look like the pics below.
THe headphone jack stays with the backplate and the connections to the board stay with the screen part of the phone.
I first used a q-tip with a small amount of alcohol to clean the connectors on both parts. Then I used some fine sand paper. BE CAREFUL NOT TO BREAK OFF OR OVER bend the leads on the input side. Once those are clean you can add a small amount of dielectric grease to the connection surfaces to prevent corrosion from happening again. You may also want to bend out the connection leads slightly so they get a better connection. The circuit board side on my phone had warped away from the leads. Put it back together and you should be in business. I just repaired mine and it seems to work great.
