Jack & Ardour updates

[leo]

I just received this email today. Last night I already performed the
updates via Tim Krone's suggested link tohttps://launchpad.net/~kxstudio-team/+archive/ppa

The result was I now have a choice of loading (from the menu popdown at the desktop upper left icon)
my usual Ardour version 2.8.14, or Ardour3.1.

My old Jack 0.3.9 is now only version 0.3.10 for some reason I don't understand.

I did the updates and added the PPAto my repositories but there was a note in the terminal and at the
website stating "Start jackd/jackdbus; then run 'pulse-jack' which will enable pulse audio support."
When I entered "pulse-jack" in the terminal, it responded "sudo: pulse-audio: command not found".

I loaded Ardour 3 and was able to record my guitar on a fresh track along with the visual active mixer volume
bar, and the track waveform showing, but the result was the same as when I did the same routine in Ardour 2.8.14,
a scratchy sound from the "click" beats. Also, the message window for Jack shows a scrolling repeating messages
of XRUNS Callback, numbers 45, 46....they change. Changing the Jack setup buffers, latency, etc, doesn't help that. Then, of course, Ardour
crashes.

Also, when I start Jack (before or after Ardour, doesn't matter) it adds Jack source, and sink to the connections.

I recommend it too. The current issues seems to occur between chair and
keyboard. It's less a user error, but perhaps some missing configuration
that has to be done by the user.

After we found out what is going wrong, we can give some hints, how to
store and restore audio sessions. I for example write scripts and use
http://aj-snapshot.sourceforge.net/ to store and restore connections, if
needed. I avoid to use jack dbus. Others from this list for sure could
give some hints, how to use session managers.

IMO Linux audio users should subscribe to
http://lists.linuxaudio.org/listinfo/linux-audio-user too, perhaps the
most important mailing list for Linux audio. There are other interesting
lists, but there's no need to subscribe to all lists, however, I suggest
to join LAU too. Regarding to the current issue Ubuntu Studio Users is a
good place to ask, so no need to ask the same question on another list.
