Paul wrote jackd 1, he has nothing good to say about jackd 2. Both he and
Robin hate Ubuntu and continue to say things like this. (ubuntu did ship a
bad version of jack in 14.04, but that would not have caused this
particular problem) The thing to remember is that Ardour.org supports only
Ardour binaries downloaded from ardour.org. This is because they can not
trouble shoot mistakes made by packagers.

We have to be able to reproduce "this problem" on our machine or at least
have an understanding of what is happening on you machine. The fact that
things are ok on a new session indicates that the problem is something to
do with the older session.
I have created a session in 16.04 using Ardour 5.0 from ubuntu repos, I
added both audio and midi tracks and recorded audio on the audio tracks
and midi information on the midi tracks. there is at least one plugin in
each track (synth or eq). I can load this session after booting 17.04 with
the ardour 5.5 as supplied but the ISO and playback the audio and midi
tracks I created in 16.04/ardour 5.0. There is no crash and I use the
supplied jackd in both cases as started by qjackctl or jack_control
While I don't run Ardour quite daily, I do development work on it to do
with control surfaces and as such run it frequently. (and also regard it
as an important application :) )
My first thing would be to (as Ralph says) run it in safe mode. The first
dialog that comes up when Ardour is started has a safe mode checkbox at
the bottom, check that and then load the session. If this solves the
problem, then one of the plugins is bad.
If not, we need to look at your setup more closely. How you run jack and

This almost looks like running Ardour with ALSA while jack is still
