Yes, it's a limitation of the XHCI (USB3) host controller driver USBXHCD.SYS that still does not support isochronous in transfers (that is: recording ...).

Paul Smedley:
I tried testing this on my miniPC - however I was too slow and the updated USB3 driver from AN has expired :(

Dave Yeo:
You can set the date back, best in BIOS, and reboot, and then set the time correctly or ask David for a new package

My God! Why didn't I think of this trick :) I have a few things going on in my personal life that are distracting me, but I re-tested this morning and was able to get sound out of a set of headphones with this driver installed. The other thing I didnt check when I was testing the other day with the default USB drivers from the latest AOS 5.1 test build, was ensuring the USB device was the default audio device, rather than uniaud <sigh> so I can't authoritatively say the new USB drivers were a requirement, but given the audio chip is attached to via USB3, I suspect it is.

Lars:
I am confused. Are you saying that you have built-in speakers or speakers/headphones attached to a connector other than USB that you think still attach to USB internally?
I certainly cannot test that, I only test devices that have a USB connector and can be plugged into a USB port. And for these devices, the audio chip is inside the device and not inside the computer.
