Other Parts Discussed in Thread: TAS5766M

各位工程师：

您好，我们是用TAS5766M在基于mstar芯片做tv板，能否提供TAS5766M在linux下面的驱动？谢谢！

    这个很复杂。第一，我们没有驱动。第二，TAS5766M是智能功放，算法参数是通过跟喇叭健模和调试后产生，参数是嵌入DSP整个代码里面，不同的喇叭的代码是不一样。换句话说，代码是跟喇叭走。不同的喇叭不能使用别的喇叭的代码，不然声音会很差，或有杂音。

    Kes，您好，

    是这样，我们发现这个芯片即使不初始化也能用。但是声音效果不好，而实际上很多tv厂都用这个芯片效果很好。要不然我把问题细化一下：

    1） Init的时候是否做哪些操作呢？

    2） 有的声音设置有各种模式，比如人声，重低音，高保真，这些i2c怎么设置

    3) 还有我们其实mstar给了5711的Init参考代码，里面有些注释，我想问一下您能否对应这个给一份5766M的，谢谢!
