hey,

I cannot output sound on a usb speaker. I have the SND_USB_AUDIO module but it’s not loaded in the kernel.I have the latest jetpack 3.3. I cannot find snd_usb_audio in /lib/modules/kernel/

here some logs:

zcat /proc/config.gz | grep -i snd_usb_audio
CONFIG_SND_USB_AUDIO=y

lsmod
Module                  Size  Used by
xt_addrtype             3595  2
br_netfilter           13924  0

The “=y” means it is built into the kernel. That feature is always there and does not have a module. “lsmod” does not show features, it shows modules (which would be “=m”).

so I am wondering why when i change the gnome sound output to the usb audio, I have no sound coming out :/
