ACL5640 doesn't work

liteblue · February 26, 2025, 4:25am

Hi NVIDIA,

我们的AGX ORIN载板使用了ACL5640，I2C已经能够检测到，I2S pinmux也检查过了，测量MCLK和I2S有信号变化。
不确定下一步该如何调试，请帮忙看下，非常感谢。

音频接线跟官方设计应该是一样的。

Please refer to Audio Setup and Development — NVIDIA Jetson Linux Developer Guide to see if can help. Thanks

是使用的此驱动源码吗：source/kernel/kernel-jammy-src/sound/soc/codecs/rt5640.c
目前无法获取5640驱动log，我在rt5640_i2c_probe函数中加了log，但内核log并没有打印，是因为驱动没加载吗？但设备树是有该设备的。

Hi:
Please try this to setup decoder settings: How can I check the Audio(I2S1) is working correctly? - #14 by jameskuo

liteblue · February 27, 2025, 6:12am

照以下方法修改后，耳机能播放了

请问MIC怎么调试？参考以下文档命令不能录音：
https://docs.nvidia.com/jetson/archives/r35.3.1/DeveloperGuide/text/SD/Communications/AudioSetupAndDevelopment.html#microphone-capture

liteblue · February 28, 2025, 2:12am

对于单mic (ALC5640 pin5)来说，是否amixer需要配置mono而不是stereo？
