Hi

I have a new system with omapl137. i used tlv320aic29 in my board. tlv320aic29 connected to omapl137 with spi1 and mcasp1. i attached the shematic.

i connected the headphone to (INT_MIC+ and MIC_GROUND) and the speaker to (AF-OUT+ and AF-OUT-).

i used mcasp1 of omapl137 for loopback on tlv320aic29.

i send below command for configuration respectively, with spi1 of omapl137:

PAGE 1 CONTROL REGISTER MAP

0x25                 0x5d20
0x26                 0xffe0
0x27                 0x0000

when i power on  the board, I heard the horn from the speaker but when i reset the board i can heard the my voice from the speaker correctly. i think that something wrong in shematic or configuration.

Please help me to fix this problem.
