To troubleshoot the issue with playing audio through AirPods connected to Jetson AGX Orin, let’s break down the steps and potential causes.

First, ensure that you have followed the instructions in the NVIDIA Jetson Linux Developer Guide for Enabling Bluetooth Audio. This guide provides a step-by-step process for setting up Bluetooth audio on Jetson devices.

Here are some potential causes for the issue:

  1. Bluetooth Connection: Verify that the AirPods are properly connected to the Jetson AGX Orin. Check the Bluetooth settings on the device to ensure that the AirPods are paired and connected.
  2. Audio Setup: Make sure that the audio setup on the Jetson AGX Orin is correct. Check the audio settings in the NVIDIA Jetson Linux Developer Guide to ensure that the audio output is set to the correct device (e.g., Bluetooth).
  3. Audio Format: Ensure that the audio format is compatible with the AirPods. The AirPods support AAC (Advanced Audio Coding) and SBC (Sub-Band Coding) audio formats. Check the audio settings on the Jetson AGX Orin to ensure that the audio format is set to one of these formats.
  4. Volume Settings: Check the volume settings on the Jetson AGX Orin and the AirPods to ensure that the volume is not muted or set too low.
  5. Audio Output: Verify that the audio output is set to the correct device (e.g., Bluetooth) on the Jetson AGX Orin. You can check this by running the command aplay -l to list the available audio devices and then use the aplay command to play a test audio file through the Bluetooth device.

To troubleshoot the issue, you can try the following steps:

  1. Check the system logs: Run the command dmesg to check the system logs for any error messages related to Bluetooth or audio.
  2. Check the audio settings: Run the command amixer to check the audio settings and ensure that the audio output is set to the correct device (e.g., Bluetooth).
  3. Play a test audio file: Run the command aplay to play a test audio file through the Bluetooth device to verify that the audio output is working correctly.

If none of these steps resolve the issue, you may want to try resetting the Bluetooth connection or restarting the Jetson AGX Orin.

In comparison to other Jetson devices, the Jetson AGX Orin has similar Bluetooth audio capabilities as the Jetson Xavier NX and Jetson AGX Xavier. However, the specific steps for enabling Bluetooth audio may vary depending on the device and the version of the NVIDIA Jetson Linux Developer Guide.

If you are still experiencing issues, you may want to try searching for additional troubleshooting guides or seeking support from the NVIDIA developer community or forums.
