Orin nano 在jetpack6.2集成音频解码器 Realtek ALC5616

PANLINQUAN · August 30, 2025, 9:07am

Hi，NVIDIA，

我们在使用Orin nano 在jetpack6.2上定制开发，在处理ALC5616遇到了麻烦。正在寻求需要NVIDIA的帮助共同调试ALC5616，希望有音频相关的的技术工程师一起探讨该问题，谢谢。

目前在论坛上了解一些与ALC5616相关的，其中根据https://forums.developer.nvidia.com/t/sample-code-for-3rd-i2s-audio-codec-which-is-succesfully-integrated-on-orin-nano-nx-platform/310839进行了调试，可惜是在JP5.1.3上的。目前在论坛上没有看到JP6.2调试ACL5616的。

首先，这里也先提供硬件设计原理图，我们也是使用I2C2与ALC5616（RT5616）进行通信的，并且目前成功识别到I2C2。

我们尝试修改了一些文件，目前看到声卡并没有注册成功，是否修改正确？是否还需要修改其它文件？

The question appears to be a mix of different topics related to NVIDIA Jetson Orin Nano and audio codecs. I’ll try to break down the information and provide a comprehensive answer.

Jetson Orin Nano and Audio Codecs

The Jetson Orin Nano is a system-on-module (SoM) developed by NVIDIA, which is part of the Jetson Orin series. It is designed for edge AI applications and supports various audio codecs.

ALC5616 Audio Codec

The ALC5616 is a audio codec chip from Realtek, which is commonly used in various devices, including NVIDIA Jetson modules. The codec supports multiple audio interfaces, including I2S, AC’97, and HD Audio.

I2S Audio Interface

I2S (Inter-IC Sound) is a serial bus interface for connecting digital audio devices. It is commonly used in embedded systems, including the Jetson Orin Nano.

Sample Code for 3rd Party I2S Audio Codec

The question mentions a sample code for integrating a 3rd party I2S audio codec on the Jetson Orin Nano platform. The code is likely related to the ALC5616 audio codec, which is supported by the Jetson Orin Nano.

Device Tree Files

The question mentions several device tree files, including tegra234-p3767.dtsi, tegra234-p3767-0000.dtsi, and tegra-codecs.dtsi. These files are used to configure the hardware components of the Jetson Orin Nano, including the audio codec.

Kernel Messages

The question also mentions a kernel message file (dmesg.txt) with a size of 594 KB. This file likely contains kernel messages related to the audio codec and its integration with the Jetson Orin Nano.

Comparison with Other Platforms

The question does not explicitly ask for a comparison with other platforms. However, based on the provided information, it appears that the Jetson Orin Nano supports various audio codecs, including the ALC5616, which is also supported by other platforms, such as the Jetson Orin NX.

In summary, the question is related to the integration of a 3rd party I2S audio codec (ALC5616) on the Jetson Orin Nano platform, and the provided information includes sample code, device tree files, and kernel messages. The Jetson Orin Nano supports various audio codecs, including the ALC5616, which is also supported by other platforms.

*** Please give the thumbs up if you get answers you like. Or provide feedback to help us improve the answer. ***

目前声卡出来了，之前是因为widge和routing对应不上rt5616的驱动，目前已经修改过来了；但是目前的情况是使用aplay播放音频文件的时候很快且没有声音。寻求帮助，谢谢。

To help diagnose the audio playback issue, please provide the following information:

Mixer Control Settings: Please share the complete list of mixer controls that were configured before running aplay (including both Tegra-specific and ALC5616 codec-specific settings).
Current Mixer State: After applying your mixer settings, please run the following command and share the output:
- ```
   $ amixer -c APE contents > ~/settings.txt
```
I2S2 Pinmux Configuration: Please verify that the I2S2 pinmux settings are properly configured in your device tree, as this is essential for the audio interface routing and share the output:
- ```
$  cat /sys/kernel/debug/pinctrl/<addr>.pinmux/pinconf-groups > ~/pinmux_<addr>
```

Pinmux settings are fine.
Mixer control settings are not done.
- Tegra controls settings, then aplay should be on pcm device id 0:
  - ```
  amixer –c APE cset name='I2S2 Mux' 'ADMAIF1' 
```
- ALC5616 controls settings, please make sure the required settings are done.

嗯按照硬件来，接上耳机；目前打开了耳机的使能。但是使用speaker-test播放，一点声音都没有，是否还有那些没有配置到呢？播放后dmesg | grep 5616 没有任何输出

I think some of the codec controls settings are missing. Please refer mixer control settings mentioned here https://forums.developer.nvidia.com/t/codec/309881/4.

Incase still issue persists,

please check the I2S signals on oscilloscope.
Share the dapm route enabled during playback.

我们目前测量了一下I2S0信号，目前一直I2S0_SCLK、I2S0_LRCK没有输出，我这边是在tegra234-mb1-bct-pinmux-p3767-dp-a03.dtsi配置了io引脚为i2s模式。

Pinmux settings seems has some issue, though function is set to I2S2 all pins are configured as tristate and input. How did you update the pins configuration, manually / pinmux excel sheet method / jetson-io tool?

PANLINQUAN · September 5, 2025, 5:55am

我了解到的是使用Jetson_Orin_NX_and_Orin_Nano_series_Pinmux_Config_Template.xlsm方式直接生成一个Orin-jetson orin nano&nx pinmux dp-pinmux.dtsi，然后询修改的地方，再同步修改BSP中的tegra234-mb1-bct-pinmux-p3767-dp-a03.dts。我不太了解，应该是使用这个方式。至于jetson-io工具，我仅仅使用查看过，查看的也是选择上了i2s2了

Sheetal.G · September 5, 2025, 6:08am

Expected tristate and enable-input values are as below. Please make sure your DT has these values. Suspecting something went wrong while using excel sheet method and Jetson-IO tool method together.

141 (soc_gpio41_ph7): 
	tristate=0
	enable-input=1
	gpio-mode=1
	function=i2s2
142 (soc_gpio42_pi0): 
	tristate=0
	enable-input=0
	gpio-mode=1
	function=i2s2
143 (soc_gpio43_pi1): 
	tristate=1
	enable-input=1
	gpio-mode=1
	function=i2s2
144 (soc_gpio44_pi2): 
	tristate=0
	enable-input=1
	gpio-mode=1

不好意思，我没有改正确tegra234-mb1-bct-pinmux-p3767-dp-a03.dts，目前已经更改，i2s信号有了，播放正常。谢谢支持。配置如下
