Hello,

 

I just received my eval board ADAU1467 but i can't have any sound. Maybe i forget something.

 

I connected Audio in ch 32-33, USBi to my computer to a USB 3 port, and a speaker on out Ch 0-1.

 

When i plug usbi and power only 1 led is iluminated : D9

Then i plug USBi and D8 is iluminated, in sigma studio USB (config hardware) is green.

 

Link, compile and download  seem to be OK, status  is "active : downloaded" but no sound.

 

I try this shematic...

 

The level move well, i tried with ch 4-5 but still no sound with a amplifier or a headset.

 

Thanks for your help

JC
