Jetson Nano - no sound cards showing on Settings

Hi all.

I am unable to see any sound cards in the Settings/Sounds tab. It says that audio is on, but I only see a “Dummy Output” option.

I setup the nano in headless mode, and I am connecting to it using RDP via WiFi (Intel 8265).

I have two sound devices connected, a Logitech H390 headset and a Syba external USB Stereo Sound Adapter. They both list under USB devices.

When I run ‘lsusb’ I get the following output:

Bus 002 Device 002: ID 0bda:0411 Realtek Semiconductor Corp.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2b Intel Corp.
Bus 001 Device 005: ID 0d8c:0008 C-Media Electronics, Inc.
Bus 001 Device 006: ID 046d:0a8f Logitech, Inc.
Bus 001 Device 002: ID 0bda:5411 Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

And when I run ‘aplay -l’ I get the following output:

aplay -l

This leads me to believe that the system is actually recognizing my hardware. Does anyone have any suggestions?

Hmmm, okay. I’ve been going at it quite a bit and I think it was simply an issue with my RDP host, and with a setting that attempted to route audio back into the computer I was using to connect. I changed that to the option that would play audio on the host device.

Note that I am not 100% sure that that was the fix. I attempted various commands for resetting ‘pulseaudio’. The point is that things are now listing under Settings/Sounds, and with some luck, it will stay that way. :)

Nevermind. Last night I got it to work, and I assumed it was an issue with the RDP software I’m using. I powered the machine off and today when I restarted it I had the same Dummy Output issue. I’m really not sure what happened. I’ll keep trying to troubleshoot and to document my progress, and will report back if I fix it. I would appreciate any pointers that you may have though.

Okay, so I went ahead and decided to flash the Nano and try again. This time I did the initial setup with a display attached and I have not yet had issues. I have also not tried to connect via RDP, but it’s a test that I would rather postpone at the moment, as I am more interested in getting to developing the synthesizer that I am trying to develop. The issue I’m having now is getting ALSA to work with Jack so that I can run Pyo. I’ll write in more detail later today when I start trying to troubleshoot that particular problem.
