您好,我正在尝试创建一个“codec_audio : sound“节点,如 decribed bellow ,但当我给板上电时,这个错误出现。
[4.977584] ASOC-simple-card sound:控制 2:0:0:AGC 攻击时间:0 已经存在
[ 5.017616] tlv320adc3xxx-codec 2-0032：aSOC：无法添加 AGC 启动时间：–16
[5.028931] ASOC-simple-card 声音：ASOC:无法实例化卡–16
[5.084242] aSOC-simple-card:声音探测失败,错误为–16
我可以做些什么来解决这个问题？
此致。
