Fritz,

Hi again, and thanks for hanging out a while at #ubuntu-studio-devel on
IRC!  We really appreciate it when people stop by and share their thoughts
and help.

I poked around a bit and have some answers (correct ones also I think) about
Pulse Audio and JACK integration in Lucid.

Since the transition of JACK into the main repositories there have been a
number of applications that now have been built with JACK support in Lucid,
notably Pulse Audio.

Therefore, if you were to download the latest Alpha image you can test that
integration.  You can find it here:
http://cdimage.ubuntu.com/ubuntustudio/releases/10.04/alpha-3/.  Please note
that I am currently suggesting that the Alpha ISO is used instead of the
daily build AT THIS TIME.  Normally you could test daily builds, which are
found here, http://cdimage.ubuntu.com/ubuntustudio/daily/, but we are
currently experiencing a slight problem with the daily builds at this time.
So, it is recommended, again AT THIS TIME, to test the slightly older Alpha
3 build.

A note about testing Pulse Audio and JACK integration:  It is my
understanding that starting JACK via qjackctl will suspend Pulse Audio by
running pasuspender.  This was the methodology that allowed JACK to serve
sound with Pulse Audio installed before Pulse Audio was built with JACK
support.  I don't know if this is the case, I will test this tonight and
report what I find.

I have been told by some of the Ubuntu Studio developers that JACK2, which
uses dbus, will be a far more elegant solution because it will allow Pulse
Audio and JACK2 to negotiate per device.

Lastly, I wanted to mention a few points about testing.  All are encouraged
to report their testing when trying out Alpha, Beta and Release Candidate
(RC) ISOs at http://iso.qa.ubuntu.com./qatracker/build/ubuntustudio/all.
Let us know if the installation went well or if you had problems.

If you have problems be sure to report a bug and link that bug in the ISO
report.  Here is a good example/tutorial:
https://wiki.ubuntu.com/Testing/ISO/Procedures

Additionally, all Ubuntu Studio users are not only encouraged to test the
Alpha, Beta and RC ISOs but also to join the Ubuntu Studio Testers Team.
You can find information here:  https://launchpad.net/~ubuntustudio-testers.
Come help us not only test Ubuntu Studio but also help develop and refine
codified testing procedures.

Once again, thank you for your involvement.

Regards,
ScottL
