Hi,
I also use Pd with FFADO (edirol FA-101), with no problem...
Two things:
1. did you started Pd with real time option? I had dio errors just like
you, and this solved the problem.
$ pd -rt #if you use midi, add -alsamidi to get ports clients in jack
alsa tab automatically
2. I noticed that Pd become really unstable with very low latency (>128
@ 48000)
hope this helps...
cheers,
