[Ardour-Users] Jack problems in Fiesty PPC

[Nicola Mattei]

Only as a temporary workaround I've found out that downgrading to
jack-0.101.1 did the trick. It works as expected with alsa, but
ardour-2.0.5 doesn't compile with it. Instead ardour-2.0.2 does, so,
for the moment, if you need a working jack and ardour2 on linuxPPC
just try this, jack0.101 with ardour 2.0.2. Probably some code changed
between 0.101.1 and 0.102.20 is causing this misbehaviour.

Peace,
Nicola
