For future readers of the list: I had to search for the meaning of an NPU and
found this reference helpful - https://www.backblaze.com/blog/ai-101-gpu-vs-tpu-vs-npu/ - no further opinions as to the company behind it.
NPU - Neural Processing Unit - chip designed for AI use.

I'm unsure what can be done - most of those are audio/video coding programs
and camera support. It might be that the move to Wayland compositing *might*
help with the xorg - or maybe that you don't run X
The problems continue ...
All the very best, as ever,
