The question is vague. You can nuke the duplicates in /usr/local/bin.
Never nuke stuff in /usr/bin. Better to uninstall RPMs using Synaptic,
provided through the Planet.

that sounds good.

What version of Ardour? The Planet? CVS tarball?

A few people have reported things like this. Personally I haven't seen
it. I have seen Ardour having connection problems when I add too many
tracks at the same time, but that doesn't corrupt the session file in

Well, possibly. I don't know the revision numbers on the two versions
of Jack. Maybe dropping back to /usr/bin was an older version and that
causes a problem. Not sure.
My over-riding suggestion to you though is to sick well within the
boundries of what the Planet installation provides for now. Don't go
wandering too far outside of that set of packages until you are more
familiar with the tools, what they do and how to understand what is
causing the problem. Take a month and jsut use what Fernando provides.
I think that you'll learn a lot about running your system and better
understand what is flaking out when somethign does.
Just my 2 cents.

Humm....I ALWAYS run with those at 0 in QJC. I didn't even notice them before!

Yes. Jack will talk to only one sound card. When you build a multi you
are going outside of Jack in terms of guaranting that both cards are
in sync. This is easier under Windows for many cards than it is under
Linux. My RME cards do fine with syncing to other sources (ADAT,
spdif, Word Clock) but I've heard that others do not. Stick with a
single card for now.

Have a great evening.
