我们基于TX1模块做开发，有一路音频line in和一路音频line out的需求，想选一款简单的codec芯片，不知道该模块对哪个厂家或者那个芯片支持的好一些，大家常用的。另外想问一下，通过I2S扩音频，除了需要驱动外，是否需要uboot做其它工作。比如在x86平台下，除了驱动外，还需要在bios里加ASL Code。
Hi 331248618,
Welcome to Jetson & Embedded Systems forum.
Please be sure to use English for your question, then other developers could understand and share their experience quickly.
Regarding your audio codec issue, please refer to Tegra ASoC Driver section from Tegra Linux Driver Package Developer Guide, you can find this document from download center - [url]https://developer.nvidia.com/embedded/dlc/l4t-documentation-28-2-ga[/url]
