What change have you made?
Please check if can find reference from NVIDIA Jetson Linux Developer Guide : Audio Setup and Development | NVIDIA Docs
Thank you for your reply. I installed the ch340 driver. This problem occurred after the shutdown and restart. Can you help me solve it? I’m going crazy
Issue still happened if unstalled the driver?
yeah, what should i do next
Actually, we’re not sure what have been done on your device.
And if uninstalled the Ch340 driver sitll happened, I will suggest to reflash your device to a clean build which is Nvidia provided JetPack SW.
