TAS5733L: There are accompaniments but no vocals when playing music

hi,

We have a project based on the amlogic platform。and PA use tas5733L.now there are accompaniments but no vocals when playing music.

Register initialization code is as follows.

What should I do with this problem?

#define DDX_CHANNEL1_VOL                            0x08
#define DDX_CHANNEL2_VOL                            0x09
#define DDX_INPUT_MUX                               0x20
#define DDX_CH4_SOURCE_SELECT                       0x21
#define DDX_PWM_MUX                                 0x25

};
