I've recently installed Windows 7 Ultimate x64 and I encountered a problem with the Line In audio feature. The audio works perfectly from windows, but when listening to the audio coming in from Line In, the Right Speaker has a muffled and distorted sound while all other speakers had normal sound. My previous Vista Business x64 (which meant right before installing windows 7) did not have this problem.
I have tried installing the Realtek drivers that i used with Vista x64. I have also tried installing Realtek's newer Windows 7 drivers, and that didn't fix the problem either.
Has anyone else had this problem and were they able to fix it?
