器件型号：TLV320AIC3110 您好！
我的 tlv320aic3110编解码器存在问题。 我在嵌入式器件启动时收到以下两个错误：
[ 10.079068] tlv320aic31xx-codec 0-0018: Unable to sync registers 0x1d-0x1d. -6 [ 10.161668] tlv320aic31xx-codec 0-0018: Failed to restore cache: -6
根据数据表、0x1d 可以是"表7-69。 页0/寄存器29 (0x1D)：编解码器接口控制2"或"表7-136。 页1/寄存器1 (0x01)到页1/寄存器29 (0x1D)：保留"。
大约一分钟后、也会出现以下错误：

最后、在暂停/恢复之后、我遇到最后这些错误：

几天来,我一直在努力寻找解决方案,但我一直未能找到任何重要的东西。 我可以做些什么或许能够更接近这些错误的根本原因吗？ 有人以前见过这样的东西吗？
如果您需要我提供的任何其他有用信息、请告诉我。
提前感谢！
