just a quick one....
i know this pops ups from time to time but....
Has anyone worked out a neat way to get firefox (flash, youtube, real audio,
etc) working with Jack yet. i would love to have a situation where i could
have Jack running permanently but this is the one thing preventing me.
cheers,

I use youtube-dl since I hate Flash and can't run it anyway (I'm on 64-bit).
And a separate sound card: one for non-JACK ALSA apps, one for JACK apps.
A Mac-based friend does a similar thing: he connects his expensive studio reference
monitors to his Presonus Firebox for his ProTools stuff, and a pair of cheap computer
speakers connected to his built-in sound card for his Safari/Firefox and iTunes/QuickTime
stuff.
I've been told there's a way to use jackplug in your .asoundrc to trick non-JACK
apps into talking to JACK (by making them think that jackplug is the default ALSA
soundcard), but I've never been able to get that working.
If I'm very desparate to see some flash-based content, I fire up qemu running Windoze
98, and that lets me listen to people's MySpace pages or deal with annoying websites
that just look like a big blank rectangle without Flash.
Did I mention that I really hate Flash? I do indeed.

You can run Flash in 64-bit browsers using the nspluginwrapper. I use it
mostly without issues on Fedora 7 x86_64

Etc.
Once it crashes, the only solution is to completely restart firefox.
Most annoyingly, I can't get all my tabs back by the usual hack of
"killall firefox" and answering Yes to "restore session?" - I have to
cleanly shut down and restart firefox. Then I can visit one or two
Flash sites before it fails again.

Well... I don't use it on my audio system, since it's only 32-bits,

flash display a blank box. But that's fairly uncommon.
The other hack, of course, is to edit the shell script that starts up
firefox and edit it such that it always runs the 32-bit version :-P

Works pretty well here (except some pretty rare situations where
nspluginwrapper seems to stop working (blank Flash videos), but
restarting the browser is enough to make it work again, no crashes at
all...)
Note that I usually run Epiphany, but Firefox seems to work without
trouble (and now I've even found a way to use a fully-opensource 64-bit
native Java 7 plugin :)

New subject: jack and flash (howto configure 2 soundcards for jack and non-jack ?)
Hello!
I'm interested to do like you did:
'And a separate sound card: one for non-JACK ALSA
apps, one for JACK apps.'
is there a howto available howto setup 2 soundcards, one for jack, one for
non-jack ?
- how do I address 'jackd' to the soundcard I want?
- can I use alsaconf to configure 2 soundcards, or do I have to edit
something like modules.conf manually?
thanks for some hints and your time....

Hello!
I'm interested to do like you did:
My system is this way. I have two sound cards - an RME HDSP9652 and an
on-board sound chip. The RME is my main card that drives the external
D/A. It always uses Jack when I'm doing anything serious. (Not often
anymore) All my funky audio needs go through the on-board sound chip.
I have the audio output of the on-board chip plugged into a pair of
inputs on the RME. I can start and stop Jack anytime and Jack can run
at a frequency different than the on-board audio since that chip's
audio is redigitized going into the RME.
Works fine for me. Distribution is Gentoo.
Hope this helps,

This has bugged me for some time now too. Your question triggered a
little quest and I've just proof-recorded some youtube snippet with
ardour. Done via pulseaudio. Here's the list:
* pulseaudio has jack modules. You get sink and source.
* For flash audio you will need a special library for flashplayer that
will hook into pulseaudio. Details on
http://www.pulseaudio.org/wiki/FlashPlayer9Solution
* For other video and audio from firefox mplayerplug-in seems to do
it. Although its docs don't say so it plays the audio from, for
example, http://streams.br-online.de/bayern2.smil (Bavarian radio,
Zuendfunk on right now. They say that would be a RealPlayer stream,
but is it really?)
-----------
This is a basic pulseaudio configuration for use with jack, put it in
~/jackd.pa:
###
load-module module-jack-sink channels=2 channel_map=left,right
load-module module-jack-source channels=2 channel_map=left,right
###
------------
Maybe tweak /etc/pulse/daemon.conf and be sure to appreciate that "#"
and ";" both mean "comment" with pulseaudio, sheesh!
Run your jackd
Run "pulseaudio -n -F ~/jackd.pa". (-n tells pulseaudio to not
use /etc/pulse/default.pa)
Run "pavucontrol" to see audio streams and in/outputs ("Adobe Flash"
stream will show up when you open one in firefox).
About it.
