OMAP L138 TLV320AIC3106 : LEFT_LOP/M and RIGHT_LOP/M are not fully powered

Hello,

I'm trying to make a simple audio loop-back program on a LOGIC PD ZOOM  OMAP L138 eXperimter kit.

But I'm facing an issue that I don't understand :

  • in registers 43 and 44, left and right DAC channels are set to not muted, and their gain is set to 0 dB
  • in registers 82 and 92, left and right DAC channels are set to be routed to LEFT_LOP/M and RIGHT_LOP/M and their gain are set to 0
  • in registers 86 and 93, left DAC, right DAC, LEFT_LOP/M and RIGHT_LOP/M are set to not muted and their output level are set to 9 dB

But in registers 86, 93 and 94, I can read that LEFT_LOP/M and RIGHT_LOP/M are not fully powered up and I don't know what I can have missed.

I'm not sure that is relevant, but in the register I can read that Left and Right DAC overflow  flag are set to 1.

Thank you in advance for any help you can provide me.
