TLV320AIC3107 Alsa audio playback with AM335x

Hi,

i'm working on a custom board based on an AM335x and a TLV320AIC3107 (class-D amplifier)

My device tree seems OK since the Alsa soundcard gets detected (You'l find my kernel initialisation log attached)

I can hear a breath when i try to play some sounds that could indicate that the class-D amp. is powering through I2C, but i can't hear any sound from the speakers.

Here is what i get when i do a "speaker-test -c2"

speaker-test 1.0.25

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 128 to 32768
Period size range from 8 to 2048
Using max buffer size 32768
Periods = 4
was set period_size = 2048
was set buffer_size = 32768
 0 - Front Left
Write error: -5,Input/output error
xrun_recovery failed: -5,Input/output error
Transfer failed: Operation not permitted

If i look at kernel log, i can see:

ALSA sound/core/pcm_lib.c:1945 playback write error (DMA or IRQ trouble?)

The driver i'm using is the one for the TLV320AIC3007 under TI kernel 3.12.10 is it OK for the TLV320AIC3107 ?

Do you have a track i can follow to find what i'm doing wrong ?

Thanks in advance for any help.
Best regards
