What sort of "clipping" issues are you referring to?

Ibasso D4 Clipping problem
This is the measurement from the Output of the AD8616
At the input of the AD8616/output of WM8740 the Signal I pump in using the computer is a Triangle wave. Level set at 100%

Sorry for the poor image, I have one hand on the probe and hand on the camera.


So confirm there is clipping.
Straight off I have not regain from my shock, this is happening to me again.


So how to solve this problem ?

1) You could up the voltage of the AD8616. (Possible to tap from the 5V amp or from WM8740, but could be noisy, need to break traces as well )
2) or reduce the Gain of the AD8616 so that the output voltage is below clipping.

The second option could be easier just change 2 resistor value. Easy mod for anyone who solder. When I finally get to do that will post the solution.

A temporary solution would be to set the volume of your computer to about 80% of max so that the clipping does not occur.

I would need to go through the D4 design again, Look like I would have to keep the D4 for a while longer as my friend would likely ask me to solve this before passing to him.

it is v well known problem in headfi... or at least in that thread..
if u are interested, u can start from page 39 onwards.
