The message "Invalid argument" is from your OS, and it looks like it is
being generated when trying to hard-link a device.  I'd suggest trying
to hard-link a device manually to see if it works:

    ln /dev/audio /dev/audiotesting123

If that fails, make sure that the CAN_HARDLINK_SPECIAL define in
config.h is not defined (just comment it out if it is, and rebuild).

Another potential way to avoid the errors would be to add --exclude=/dev
to your options (as long as you don't require the backing up of your
device files).
