Hello, I want to power down Voice/Bluetooth sidetone PGA of TWL5030. I set the VSTPGA Register/BTSTPGA Register to 0x00,but it seems that the Voice/Bluetooth sidetone PGA still work, and even set VSTPGA/BTSTPGA to Mute,there still have sidetone come out.

How can I power down Voice/Bluetooth sidetone PGA? I don't need sidetone.

Are you sure, that the sidetone is added by the VSTPGA/BTSTPGA? Could you check, if you accidentally left either the analog loopbacks enabled (or digital loopbacks)? Check for these: Right1/2 Analog Loopback, Left1/2 Analog Loopback, Voice Analog Loopback, Left/Right/Voice Digital Loopback

Could you describe your scenario (uplink, downlink routing, etc)?
