Have you considered that freebob could be the problem?
I don't
understand why you expect bleeding edge software to be stable enough for
live use...
Desperation :)
Seriously though, as mentioned I did quite a hump jump at Zyn, I assume
I simply ran out of CPU cycles, combined with a certain instability Zyn
already had when I was using it with ALSA, mainly in connection with
loading patches. At 44.1 (instead of 96) things work fine now.
FreeBoB is amazingly stable, by the way.
