[Unitree Go2] Access to Microphone

Sensors
1

Hello,

I’m using a Go2 EDU Plus with the expansion dock (Jetson Orin NX) and need to capture audio synced with the robot’s motion.
I need to capture acoustic data through the go2
Is audio recording accessible via built-in microphone from Go2?

My questions:

  1. Does the Go2 EDU Plus (with expansion dock) have a functional onboard microphone that is accessible to the user via SDK, ROS2 topic, or any API?
  2. If so, what is the correct method to access/stream/record from it (e.g., ALSA device name, ROS2 topic, ffmpeg/PulseAudio configuration)?

Robot info (if needed for your reference):
Model: Go2 EDU Plus
SDK: unitree_sdk2py
