How to use tinymix and tinyplay?

jacklu — Thu, 27 Aug 2015 03:25:33 GMT

Hi expert,

我们目前android版本是5.0.2(l5.0.0_1.0.0-ga : base on Android 5.0.2_r1), kernel版本： Linux version 3.10.53

碰到一些audio codec(WM8962)的问题，想尝试debug。

可以帮忙提供一些test&DEBUG方法么？

请问是否可以提供speaker(dual) 、 headset的操作方法（使用tinymix）。

Thanks!

BRs,

Jack

Freescale is responsible for cpu dai.

Codec vendor is responsible for codec dai.

Customer is responsible for machine driver, which should follow the alsa asoc framework.

No any direct call to the cpu dai to code dai.

And it is alsa development, please be aware of those.
