Has there been any progress on this matter?
I've had the exact same problem with my old chieftec case, but I used some el cheapo 3.5" sound panel in there.
All I had to do was to put duct tape on the parts of the front panel which were in contact with the pc case, so that it was isolated.
this method obviously won't work with the P182's front panel thing.
All I know is that it's being caused by bad shielding.
The hissing is getting louder when I play 3D games, probably because the gfxcard is switching to 3d mode which results in a stronger magnetic field... you know... more juice=stronger induced field and all that.
But I also get that hissing sound or more like a whirr, when I scroll through websites or when I drag around windows.
I can eliminate the sound by putting my finger on the ground wire... but that's not a very handy solution.

I've ordered a 40cm extension cable for those internal HDAudio+ac97 pin connector things, because I've read on another forum that some people resolved this exact same (or a similar) problem by relocating the cable inside the case (like behind the gfx card and cpu) and somehow bypassing the magnetic field which is causing that interference.
Or is there any other known solution, like a fixed new revision of the sound panel?
