====== NVIDIA Jetson AGX Orin 64GB 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"**:

<code bash>
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 


</code>

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.

Buggy or weird behavior of Audacity on Linux. 

**Don't do that:** "sudo snap connect audacity:alsa". In case you did you can "sudo snap disconnect audacity:alsa".

Don't use the button "Access ot ALSA has been granted."

**Rather click on button "Start and do not ask again"** when Audacity comes up.
