I bought an "iPanel Deluxe" a few months ago and found it was not all it was suppose to be. All problems I encountered were audio related problems. The iPanel was installed to a model P4T533-C motherboard. The main problem was a high pitch, whining noise on the line-out and line-in jacks on the iPanel. I exchanged the unit for another new one but the problem was still there. Then I found that when I disconnected AFPANEL connector the noise stopped. So for a while I ran without the LED read out and the IR. It was not necessary at the time. So one rainy day I pondered iPanel problem once again. If you have worked with audio equipment you know most noise problems are associated with poor grounding or shielding. Well anyway I may have found a fix for the problem and ASUS overlooked this issue. After checking the circuit board located behind the face plate of the iPanel I found that the grounds for the LED and IR were isolated from audio section. But once the board is screw mounted, the metal frame closes the circuit connecting the isolated grounds. There are three mounting screws. I found the center screw was where the audio ground is. I used a nylon screw and some electrical tape on the metal part of the frame to prevent contact and that was it! The other problem was the microphone input switching using the "Sound Manager" was reversed between microphone and center/subwoofer-out. I downloaded the latest drivers from ASUS and that fixed it. This problem was only on the iPanel jack not the motherboard jack. With the negative responses I have seen posted on this group about the iPanel maybe there is some hope here for some owners. Good Luck! Anthony
