tda7439 arduino nano controlled

Hi,
Im been working on a project I found on instructable, with arduino based amplifier, and I been having some problems with the code I think,
When i send i2c bus scan, i receive 0x44 so there is contact and the clock work on the bus and the lcd screen.
get sound for 1ms when i plug in power to the board.
all solder joints are good, this is the second card I build with new components.

 

I hope there are somebody who understands c++, using IDE 1.0.6
I might suspect the code on the libary for wire, write ...

or maybe some problems in the eeprom section..

 

 

The amp sound very good, and trying to get the microcontroller installed with remote.

 

here is the link to the project.

 

nikotronic

 

best regards Niklas.
