Dell Studio HDMI and Sony HD tv connection problem

Hello,
I was wondering if you found an answer to the problem with the Dell studio HDMI. We are having the same problem only we have a 42"SONY LCD HD screen that is also new. We have tried to check all setting on the computer as well as updates and nothing seems to help. 2/9/11

Sorry I am new to this type of posting. I am the one with the problem with the Dell Studio computer HDMI problem when connecting to the HDMI port on a new SONY TV. The volume problem either gets real loud and static or the volume goes out completly. It keeps going in and out.
We have two children that are in IT and they can't seem to come up with an answer. They have tried settings and updates and nothing seems to work. We are desperate. Please help!
