Sorry, can't answer any of those questions... but how are you connecting 
your Audiofire? I have one here sitting unused because the one laptop 
that had a Firewire connection died a decade ago. I have a desktop 
system available, so a PCIe-Firewire card would be an option, or my Dell 
laptop with USB-C.
