    Hi Yuan

       First to confirm with you, there's both E and without E version for TAS6424 and TAS6422, do they test both of the device same with E version, or without E version? 

       There's possibility the noise coming from audio source, as TAS6424 only use 2 channel data may not include noise, but the other 2 channel only used by 6424 may have.

       Except this possibility, the problem may not happens on the I2S, there's not too much difference between these two devices. We may check what is difference on the PCB board.
