Hi Nvidia,

I have Samson Go Direct usb mic.
On fresh installed system l4t 24.2.1 mic is present in sound settings as input device and works fine.
But on l4t 28.1 i can’t see usb input device in sound settings.

Here is dmesg after plugin usb mic:
[ 886.265661] usb 1-3.1: USB disconnect, device number 4

Possibly there is a driver by default in R24.2.1 which just isn’t configured in R28.1. There would be a “card 2” and not just “card 1” if the headset had triggered load of a driver. My headset does trigger card 2, which also triggers module loads. What is your “lsmod” showing with the headset connected? These are the ones my headset triggers on R28.2:

snd_usb_audio         183258  2
snd_usbmidi_lib        26147  1 snd_usb_audio
snd_hwdep               8187  1 snd_usb_audio

I have checked it.

Both kernel provided by LeopardImaging with csi camera support.
Will try to rebuild kernel.

Yes, my kernel has:

CONFIG_SND_USB=y
<b>CONFIG_SND_USB_AUDIO=m</b>

I have made kernel with CONFIG_SND_USB=y,CONFIG_SND_USB_AUDIO=y in tegra21_defconfig and usb mic works now.
Closed.
