设备环境：
VIM3 android最新固件
问题描述:
A311D hdmi audio默认是绑定到tdmb 然后通过spdifout同步输出到HDMI audio。原配置如下：
aml_tdmb: tdmb {
compatible = "amlogic, g12a-snd-tdmb";
#sound-dai-cells = <0>;
dai-tdm-lane-slot-mask-in = <0 1 0 0>;
dai-tdm-lane-slot-mask-out = <1 0 0 0>;
dai-tdm-clk-sel = <1>;
clocks = <&clkaudio CLKID_AUDIO_MCLK_B
&clkc CLKID_MPLL1
&clkc CLKID_MPLL0
&clkaudio CLKID_AUDIO_SPDIFOUT_CTRL>;
clock-names = "mclk", "clk_srcpll",
"samesource_srcpll", "samesource_clk";
pinctrl-names = "tdm_pins";
pinctrl-0 = <&tdmb_mclk &tdmout_b &tdmin_b>;
mclk_pad = <0>; /* 0: mclk_0; 1: mclk_1 */
/*
* 0: tdmout_a;
* 1: tdmout_b;
* 2: tdmout_c;
* 3: spdifout;
* 4: spdifout_b;
*/
samesource_sel = <3>;
};
现在开发板tdmb I2S接口用于其他音频接口。通过音频改由aml_tdmc I2S方式输出到hdmi 但是没有声音？流程来看没有问题 配置以及log如下 EE_AUDIO_TOHDMITX_CTRL0寄存器来看是对应的 请问是否还有其他问题 谢谢：
aml_tdmc: tdmc {
compatible = "amlogic, g12a-snd-tdmc";
#sound-dai-cells = <0>;
dai-tdm-lane-slot-mask-in = <1 0 0 0>;
dai-tdm-lane-slot-mask-out = <0 1 1 0>;
#dai-tdm-lane-oe-slot-mask-in = <0 0 0 0>;
#dai-tdm-lane-oe-slot-mask-out = <1 0 0 0>;
dai-tdm-clk-sel = <2>;
clocks = <&clkaudio CLKID_AUDIO_MCLK_C
&clkc CLKID_MPLL2>;
clock-names = "mclk", "clk_srcpll";
pinctrl-names = "tdm_pins";
pinctrl-0 = <&tdmc_mclk &tdmout_c &tdmin_c>;
mclk_pad = <1>; /* 0: mclk_0; 1: mclk_1 */
i2s2hdmi = <1>;
};
