I'm on Debian testing nicely tweaked (a.k.a. AVLinux), which means all
sound is pure direct ALSA, except when I turn on Jack and run something
explicitly through it. The question is: Is there any reason why I
should not be running all audio through Jack? I heard that through
.asoundrc one can achieve this quite easily, and it strikes me as a way
to speed up the process of setup for a gig, unless there are downsides I
don't understand?

I do that in ubuntu jaunty:
there's a mechanism in ALSA that lets you use jack as output for ALSA
only applications:
http://alsa.opensrc.org/index.php/Jack_(plugin)
I have this on my ~/.asoundrc
pcm.!default {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
This means that the ALSA "default" device should be redirected through
the "jack" device.
For this to work I had to recompile the package libasound2-plugins,
which did'nt include the alsa jack plugin in stock ubuntu.
And it also means that when you're not running Jack, ALSA applications
will complain (but you can always move the .asoundrc somewere else to
restore the original functionality)
I'm able to use almost all sounding applications through jack this
way, including skype and the flash plugin for firefox (from version 10
up). Those are not realtime safe, so they make some xruns... But I
turn on jack in the morning and use it all day long and all is working
quite well.
J.E.B.
Hope this helps
Ciao

I don't use those proprietary applications, but as you said, "almost
all" and "make some xruns" are typical problems with the ALSA JACK
module, which never was any good. I believe you will see better
performance running through pulseaudio and then output to jack. All ALSA
applications will then send their audio to pulseaudio which then sends
it out on JACK.

libxine is generally better than the alsa Link I find. So if I have a choice
between the two I go for the former.
The alsa jack plugin works well for boodler and I am told it works well for
skype. It doesn't seem to work well for movie players and the like - nor
have I been particularly happy with mplayers jack interface. (VLC doesn't do
jack on Ubuntu and I can't be bothered building it from source)
It would be really nice if gstreamer and pulse-audio played better with
jack.

Oh, It looks like LAU it's your own personal space now, where you can bother
other people complaining about nothing with your own silly thoughts.If you
have to whine or complain about my behaviour please write to
anomalsound(a)gmail.com and don't fill this public space with pointless stuff.
This will be my last public reply.

To be honest I hadn't tried for several reasons
1) Ubuntu makes running anything with jack a LOT harder than it needs to be.
I would need to compile jack support in myself (my understanding is that
this policy will change for 10.04 and it better - even Debian unstable is a
lot easier to set up for pro-audio at the moment)
2) the jack plugin is resides in gstreamer-plugins-bad package and the last
I heard about the gstreamer devs about it was that the code did need a lot
of extra love.
3) While I like the idea of gstreamer I have found libxine generally does
the job with fewer resourses and fewer problems. The amarok devs who used to
develop backends for both seem to hold the same opinion (and the phonon devs
give a similar reccomendation) . As such I have tended to overlook gstreamer
based programs and go for the alternatives, since I run KDE all the default
choices are non gstreamer anyway.
Having said all that. Hearing reports that gstreamer do now play fine with
jack is just what I wanted to hear. It means that I can start exploring the
gstreamer universe and see what it really has to offer :)

To make rhythmbox on Ubuntu Jaunty use jack, open gconf-editor and set
"/system/gstreamer/0.10/default/*audiosink" to "jackaudiosink".
I guess that the problem is that on Ubuntu the default jack devices uses
dmix plugin, thus jack will not get the device exclusively, and the
gstreamer autodetect sink will not automatically switch to jack but stay
with alsa instead.

Uhh wait..I don't get the problem here. You could just not do anything else
other than your audio work and still use the alsa jack plug. Then change
every app's output to jack; those that can't will output fine via the plug.
I don't know about other DEs but in KDE nothing disturbs me as long as I
don't run anything non-proaudio. If you don't use a DE then the more reason
to not fear anything.

I'm very sorry to hear that, it was just a joke anyway.Sometimes i wonder if
it's more annoying some kind of stupid/irritating/unuseful/pointless answers
i can read on LAU that actually waste my/our time (i could give you a huge
list of those if you need it) or a little joke like this.
Maybe you should also look at those people.
Thank you for your attention

One reason not to use jack for all your sounds is you don't want mouse
clicks, OS warnings and "you've got mail" sounds going to your audience
or recording. Pulseaudio is intended to handle those regular user sounds
but can have terrible latency and lack of control for the musician, even
with the pulse-jack connection.
LASH can save your jack and audio application connections and settings
and can restore them fairly quickly, give it a try.

Why not?
I have read somewhere that someone (one of the TOPLAP dudes, I think)
actually made a performance using only those.
But anyways, I get your point (and I agree), however, I have been
performing with a computer for 13 years or so and a trick I learned
very early on (like, after the first rehearsal) is that one turns off
all annoying sounds of the desktop on a computer that one intends to
do audio with. Does it really have to be governed by the audio server
I choose to use? I think that I prefer to turn all that stuff off
forever.
And the all time winner of the most annoying sounds is the a major
chord from apple computer when you boot it... Especially through the
PA system when you least expect it.

I run with all unnecessary services completely disabled (network is
only re-enabled if I want to upgrade something), the lightest and
simplest possible desktop, with zero cue sounds or special graphics
effects. Pulseaudio, if it's there, is the first thing to go straight
in the bit-bucket.
