Raspi B / DAC soldered sound out of one speaker only

Hi Guys,

I received my dac yesterday and soldeed it.
tried to play some stuff on volumio and it works well .... on one speaker

BUT if take half of the white rca out so only the center pin is plugged (doesn't touch the outside female rca sleeve) it does play on both speakers

Any ideas ?
(please excuse my english)

Thanks guys for helping
