AM5728: TLV320AIC3104 I2C Communication

Hi,

I am wanting to write to the registers of the audio codec from user space using i2c. 

i2cdetect -r 4 provides the audio codec on 0x18 but when I try to read or write I get that the Device or resource is busy. 

Any recommendations to enable changes for the AIC3104?
