NVIDIA Jetson AGX Orin 64GB Setup

Setup VNC server on the Jetson developer kit

I am following the howto: https://developer.nvidia.com/embedded/learn/tutorials/vnc-setup

ReSpeaker USB Microphone Array

Flashing new firmware according to https://wiki.seeedstudio.com/ReSpeaker-USB-Mic-Array/

I am flashing the “1 channel firmware”:

sudo apt-get update
sudo pip install pyusb click
 
git clone https://github.com/respeaker/usb_4_mic_array.git
cd usb_4_mic_array
 
# if you want to use 1 channel,then the command should be like:
sudo python dfu.py --download 1_channel_firmware.bin
 
# Alternative, did not work for me (mic not showing up in GNOME):
# sudo python dfu.py --download 6_channels_firmware.bin  # The 6 channels version

Then disconnect ReSpeaker from USB and reconnect. The mircophone occurs in the GNOME audio settings menu.

Install Audacity

To test the microphone and to record audios for training the LLM and ASR.

Don't do that: Grants access to alsa sound system to Audacity:

sudo snap connect audacity:alsa

This does not work! Rather click on button “Start and ask next time” when Audacity comes up.
