As for FW solution, FreeBob project's site states
FA-101 works, but
I'd like to know about minimal possible latency. And does it have any
restrictions on buffers/frequency setup?
Yes, the FA-101 works but I can't tell you the numbers for latency. What
do you mean with restristrions on buffers (=latency?)?
All sampling frequencies should work but I think we have only used the
44,1 kHz, 48 kHz and 96 kHz so far because
we consider the 192 kHz more as marketing gag :)
Currently, I would not recommend to use our driver for a critical stuff,
though it looks very good.
Hope that helps.
cheers,
