My point was A7N8X DELUXE versus NON-DELUXE. It's not the same sound chip. The answer might reside there! Cause the NON-DELUXE use a "cheap" stereo sound chip only.
When you talk A7N8X, it's important to mention DELUXE or not and Rev 2.0 or not. This helps sort out the solution to common problems.
Probably, another useless post from me! But I like to talk!
