Interesting.
My comment about the Apple/Protools was my assumption based on little research. I avoid Apple products completely now that I'm out of the corporate world...read completely ignore. So thanks for the info.
But, I use Ubuntu Studio. In 20.04 they have basically dropped support for things like ffado.
I've gone round and round trying to get the FW cards to work in 18.x and 19.x.
It is hard to find interface boards for FW, let alone the ones with TI chipsets that work correctly.
So, I've kinda given up trying...especially since I don't really need them for what I do anymore.
Maybe they work better with alsa. But, last I tried that didn't seem to play nice and I don't know of a low level control interface (like ffado-mixer) to configure them.
Admittedly, after fussing with them for a month or so last year, I just haven't looked at them since.
