Qualcomm ASOC_Speaker 修改mixer_paths_qrd_sku3.xml调试记录

1、tinymix log 检索

    MI2S_RX Channels|RX1 MIX1 INP1|RX2 MIX1 INP1|RDAC2 MUX|HPHL|HPHR|Ext Spk Switch

2、XML文件配置

2.1 从耳机双声道路径经过的Speaker及其对应的原理图

 

    <path name="speaker">
         <ctl name="MI2S_RX Channels" value="Two" />
         <ctl name="RX1 MIX1 INP1" value="RX1" />
         <ctl name="RX2 MIX1 INP1" value="RX2" />
         <ctl name="RDAC2 MUX" value="RX2" />
         <ctl name="HPHL" value="Switch" />
         <ctl name="HPHR" value="Switch" />
         <ctl name="Ext Spk Switch" value="On" />
    </path>

2.2 从耳机单声道路径经过的Speaker及其对应的原理图

 

    <path name="speaker">
        <ctl name="MI2S_RX Channels" value="One" />
        <ctl name="RX2 MIX1 INP1" value="RX1" />
        <ctl name="RDAC2 MUX" value="RX2" />
        <ctl name="HPHR" value="Switch" />
        <ctl name="Ext Spk Switch" value="On" />
    </path>

2.3从模块路径直接连接的Speaker及其对应的原理图

 

    <path name="speaker">
        <ctl name="RX3 MIX1 INP1" value="RX1" />
        <ctl name="SPK DAC Switch" value="1" />
    </path>
