new Pi 3 with Pi Fi DAC+ 2.0 don`t work (solved)

[grunff]

Hi,
I am old hi fi sound music enthusiast, and I recently obtained Pi3 (RS) and PiFi DAC+ with TI 5122. (all from recommended aliexpress vendors).
I assembled hardware and prepared SD with RuneOS 0.4, and boot successfully.
Obtained normal sound from USB flash disk on 3.5mm out before change to I2S.
Next I changed all recommended changes in config.txt and /etc/modules/ .... and asound.conf in /etc/
and can change audio output interface in MPD to HiFiberry dac+ I2S ... and

I HAVE NO SOUND on DAC output. its something like distorted rumble. and I don't know where is the catch 22
What I need to do more or change ?????

(amp working well on aux input where is connected NAD cd player and changed it with dac. Song is Herbie Hancock Imagine MP3 24bit 44.1 kHz 320kbps)

I will very appreciate your help..
regards
Goran

SOLVED .... power adapter didnt work well. with another one, DAC works ...

thx Frank for your fast answer.
Today I tried with new fresh img 0.4 and only changes in config.txt

uncommented lines

dtparam=i2c_arm=on
dtparam=i2s=on
device_tree_overlay=hifiberry-dacplus

I didnt change audio output of Pi3
#snd-bcm2835

and I have normal sound on 3.5mm Pi3 out (when its selected in MPD)
but on the DAC all two outs 3.5mm and rca still remain that distortioned rumble.

If you dont have any idea what is it, tommorow I will open and disassemble it to check the hw ... and take a photo.

tnx and regards
Goran
