We are using a TPA5050 and are hearing a "chirp" in the audio as we adjust the delay. To adjust the delay we basically read a voltage from a pot via an a/d in a PIC and write the delay value as shown in the PIC code below. We only use the left channel and mute the right channel. It seems the "chirp" may be a result of the I2C write. Any ideas on alleviating the "chirp"?
data[0] = 0x01; //starting register 0x1
data[1] = 0x80; //1
data[2] = 0x00; //2
data[3] = 0x00; //3
data[4] = (UINT8) ((potValue & 0x1F00) >> 8); //4
data[5] = (UINT8) (potValue & 0x00FF); //5
data[6] = 0x00; //6
data[7] = 0x00; //7
data[8] = 0x01; //8
I2C_Send(address, data, 9);
