Hi
I have a new system with omapl137. I used tlv320aic29 in my board. this codec connected to omapl137 with spi1 and mcasp1. I attached the shematic.
I connected headphone to (INT_MIC+ and MIC_GROUND) and speaker to (AF-OUT+ and AF-OUT-).
I used mcasp1 for loopback.
I send below command with spi1 for configuration respectively.

when i power on the board, I heard the horn from the speaker but when i reset the board i can heard my voice from the speaker correctly. I fixed the reset circuit based on below proposed block diagram.

when i power on my board everything is ok, but this problem is still not resolved. I think that something wrong in shematic or configuration.
Please help me to fix this problem.
