Arduino library for WTV020-SD-16P audio module

rulicos:
I´m trying to conect the module like point 8.8 of datasheet. Reset works but when a press play, led go off and i heard a noise for 1-2 second, then stop and led go on. I try with 4 differents sd (two of 2gb kingstom and scandisk, one of 256mb and other of 4gb)

I try with 2 speakers of 8 ohms and 3w and 1w, and somes buzzer and little speakers. I try with mnay audio example form hear an otrher from youtube

I think ALL problems with this module are because of the power supply. SD cards need more than 3.3V to work (it's in their specification).

Using this power supply, all my problems disappeared:
