Tony, First of all, I haven't replaced my main board yet so I can't give a report yet on that. However this came to mind for us to think about and discuss.

When you first turn on the Audya, there is a little pop up screen for a split second at the end of the boot up that says:

" Loading Audio Resources " As that screen disappears, you hear or at least I hear a little " Clicking Noise".

The noise seems to be coming from the top of the keyboard rather than from the bottom.

The computer board or boards used to control all the push buttons, etc. have never been to my knowledge, discussed on SZ.

We are all searching for the cause of the Audio out problems.

Could the problem just maybe be in the top board or Boards?????

Skude and others have replaced the Sound Board and the Main Board and the HD etc. and still have audio out problems.

But nothing has ever been said about boards located in the top of the keyboard.

What are your or others thoughts on this?

Jim
