Possible to daisy chain Firewire Interfaces for more I/O?

It seems like I've heard this can be done, but if so, how do you do it?

I currently use JACK since it seems to be the only way to run Firewire on Ubuntu 22.04.

Audio Interfaces above a price point generally have ADAT In and Out, maybe that's what you're thinking about

Some firewire interfaces have two firewire ports, one for the computer, one for connecting to another card. It works (ffado / jack only sees only 1 card with all i/o), at least with some cards (saffire pro40 does). If I'm not mistaken it's not very reliable when chaining different brands (models/chips ?).

In my case it's 2 similar M audio interfaces (2626 and a 610) which are interchangeable when used alone. Basically the same interface just different amounts of IO.

Then try connecting the 2626 to both the computer and the 610, start jack in firewire mode and let us know how it goes !

Thanks, I didn't know that. I have a pro40, forgot it had two FW sockets. Maybe that explain why in pipewire it sees a duplicate set of input and outputs that do nothing.
