I am using ARD-AUDIO-DA7212 shield to record voice from analog Mic and output to headphones.
I can successfully output voice to headphones by bypassing ADC/DAC modules (analog only).
But when I want to pass data over ADC/DAC modules (skipping DAI output) I can't hear nothing in headphones.
I saw that when SR register set to 8, 12 or 16kHz, nothing happens.
But when I set SR register to 44.1 or 48kHz, I hear only noise from headphones.
MCLK = 12MHz
PLL_CTRL = 0xC4
DAI = slave mode
DIG_ROUTING_DAC = 0x00
Please help me with proper codec Initialization.
