I run 13.04 Pulseaudio is 1:3.0-0ubuntu6

If you read carefully, you may find, that the bug refers to a situation,
where jackd spawns the following error:

ATTENTION: The playback device "hw:0" is already in use. Please stop the
application using it and run JACK again

I have a problem, that spawns this:

 ERROR: cannot register object path
"/org/freedesktop/ReserveDevice1/Audio2": A handler is already registered

The only "fix", I could find so far is completely removing pulseaudio
(recommended by FalkTX), seems not the most elegant way to handle this
to me.

What I was trying to say here is, that it would be great, if a
distro-variant, that promises ease of use for multimedia-producers,
concentrates on making the distro working as expected in the first
place. Before discussing easy to go fun stuff like what DE will we use
and how shall it look like?

I am sure, if the team would concentrate on show-stoppers, the users
would be glad to help fixing them and be it by spreading word on such
problems to become a PITA for those, who are qualified enough to fix. I
am not and most users are not capable to fix low-level bugs as well....

Do you have a statistic on how many people out there use US for

Anyway: any person, that uses Win or Mac for that that tries US and is
encountering this problem will switch back and maybe consider using
Linux next year or never....
