[Ardour-Users] Jack problems in Fiesty PPC

[Nicola Mattei]

I can confirm _exactly_ the same results with feisty (and jackd
0.102.20) and gutsy (jackd 0.103) PPC on an ibook and a powerbook G4
(snd_powermac alsa driver) and it seems we are not the only ones:

If there's something I can do to debug this just ask and I'll try my best.

Thanks,
Nicola
