[RK3288][Android6.0] 调试笔记 --- RT5640播放时的Codec寄存器列表

Platform: Rockchip
OS: Android 6.0
Kernel: 3.10.92
Codec: RT5640

此文给调试RT5640播放无声音的朋友做参考。

RT5640用的是RT3261的驱动.

speaker接的HPOL和HOPR, 因此走的是headset通路。

对应config配置在hardware/rockchip/audio/tinyalsa_hal/codec_config/rt3261_config.h中.

const struct config_control rt3261_headset_normal_controls[] = {    //disable ASRC    {        .ctl_name = "ASRC Switch",        .str_val = "Disable",    },            {        .ctl_name = "Speaker Playback Switch",        .int_val = {off, off},    },    {        .ctl_name = "HP mute Switch",        .int_val = {off},    },    {        .ctl_name = "OUT Playback Switch",        .int_val = {off, off},    },    {        .ctl_name = "Modem Input Switch",        .int_val = {0},    },    //OPEN ROUTE    {        .ctl_name = "DAC L2 Mux",         .str_val = "IF2",    },    {        .ctl_name = "DAC R2 Mux",         .str_val = "IF2",    },    {        .ctl_name = "Mono dacr Mux",        .str_val = "TxDC_R",    },    {        .ctl_name = "DACR Select",        .str_val = "IF2_DAC",    },    {        .ctl_name = "Mono DAC MIXL DAC L2 Switch",        .int_val = {on},    },    {        .ctl_name = "Mono DAC MIXR DAC R2 Switch",        .int_val = {on},    },    {        .ctl_name = "OUT MIXL DAC L2 Switch",        .int_val = {on},    },    {        .ctl_name = "OUT MIXR DAC R2 Switch",        .int_val = {on},    },    {        .ctl_name = "HPO MIX HPVOL Switch",        .int_val = {on},    },    //dBscale-min=-46.50dB,step=1.50dB,min=0,max=31    {        .ctl_name = "Headphone Playback Volume",        .int_val = {31, 31},    },    //dBscale-min=-65.625dB,step=0.375dB,min=0,max=175    {        .ctl_name = "Mono DAC Playback Volume",        .int_val = {175, 175},    },    //speaker normal    {        .ctl_name = "SPK MIXL DAC L2 Switch",        .int_val = {off},    },    {        .ctl_name = "SPK MIXR DAC R2 Switch",        .int_val = {off},    },    //speaker incall     {        .ctl_name = "Stereo ADC MIXL ADC1 Switch",        .int_val = {off},    },    {        .ctl_name = "DAC MIXL Stereo ADC Switch",        .int_val = {off},    },    {        .ctl_name = "Mono DAC MIXL DAC L1 Switch",        .int_val = {off},    },    {        .ctl_name = "SPK MIXL OUT MIXL Switch",        .int_val = {off},    },    {        .ctl_name = "OUT MIXR DAC L2 Switch",        .int_val = {off},    },    {        .ctl_name = "SPK MIXR OUT MIXR Switch",        .int_val = {off},    },    {        .ctl_name = "Stereo DAC MIXR DAC R2 Switch",        .int_val = {off},    },    {        .ctl_name = "LOUT MIX DAC R1 Switch",        .int_val = {off},    },    {        .ctl_name = "Stereo DAC MIXL DAC L2 Switch",        .int_val = {off},    },    {        .ctl_name = "LOUT MIX DAC L1 Switch",        .int_val = {off},    },    //bt incall    {        .ctl_name = "DAC MIXL INF1 Switch",        .int_val = {off},    },    {        .ctl_name = "Stereo DAC MIXL DAC L1 Switch",         .int_val = {off},    },    {        .ctl_name = "OUT MIXL DAC L1 Switch",         .int_val = {off},    },    {        .ctl_name = "LOUT MIX OUTVOL L Switch",          .int_val = {off},    },    //close other mixer     {        .ctl_name = "OUT MIXL REC MIXL Switch",        .int_val = {off},    },    {        .ctl_name = "OUT MIXR REC MIXR Switch",        .int_val = {off},    },    {        .ctl_name = "DAC MIXR Stereo ADC Switch",                     .int_val = {off},    },    {        .ctl_name = "HP mute Switch",        .int_val = {on},    },};
