Hi ,
We checked the TLV320AIC3254 Application Reference Guide, the PGA gain is controlled by the AGC and cannot be controlled by ourselves..
Can you help check which of the following registers are invalid when AGC is enabled?
Page 0 / Register 83: Left ADC Channel Volume Control Register - 0x00 / 0x53 (P0_R83)
Page 0 / Register 84: Right ADC Channel Volume Control Register - 0x00 / 0x54
Page 1 / Register 59: Left MICPGA Volume Control Register - 0x01 / 0x3B (P1_R59)
Page 1 / Register 60: Right MICPGA Volume Control Register - 0x01 / 0x3C (P1_R60)
Thanks.
