So many times I'm sitting here with Jack running along with various apps
and I end up downloading an mp3 which to listen to I just want to type:
play downloaded.mp3
but I can't because Jack is running and Sox does not know Jack AFAIK.
Are there any similar command line programs for doing this through Jack?
I'm only interested in the play facility of sox.
Or a way to get round it?
Cheers,
James.

Hi!
the sndfile-programs now have a jack enabled play program, but I'm not sure,
if libsndfile supports mp3.
Then there's ecasound, which can be installed from all major distros as
well. It plays mp3 using mpg123 or mpg321 and its own JACK capability.
You could be dirty and use a pipe with sndfile-jackplay.
Also you can create an ALSA device, that uses JACK and then use sox directly
if you like or a concatenation of mpg321 and aplay.
The JACK plugin would look something like this, in your ~/.asoundrc or
/etc/asoundrc (I think they changed the system wide name some time back):
pcm.!default
{
type plug
slave
{
pcm "myjack"
}
}
pcm.myjack
{
type jack
playback_ports
{
0 system:playback_1
1 system:playback_2
}
capture_ports
{
0 system:capture_1
1 system:capture_1
}
}
Admittedly, this way you can't use ALSA directly, not with your default
output, but I guess, you've got JACK running all the time anyway. :-)
Kindest regards
Julien

Hi Julien,
I rather like this :)
Brilliant how anything outputting sound just pops up in qjackctl now!
Ahhhh, even flash audio. I'm in audio pirate's heaven! No too soon I
don't want to die!
Is there any way at all, that instead of these things connecting to the
default playback1/2 ports they could auto-connect elsewhere?
Cheers,
James.

Hi!
You could specify any playback or capture ports I think.
Kindest regards

No, you don't;).

There is a way, but not using that crappy ALSA JACK plugin.
You could use pulseaudio with JACK, so that ALSA apps talk to pulse, but
outputs audio through JACK.
By setting up a map file in pulseaudio, you can let different ALSA apps
output on different JACK ports.

Is there an ui for this here setting up a map file process you refer to?

With the ALSA JACK plugin, I am forced to have JACK running, as mentioned
by Julien. Which is not so great for the times I don't have JACK
running (which ranges between 25%-75% of the time depending on what I'm
doing).
Is PulseAudio clever enough to realize when JACK is not running and route
the audio accordingly?
Cheers,
James.

Yes.
If you use pulse audio as your default sound manager and have a script
to disable, connect and disconnect from jack when jack is
started/stopped you can keep pretty much forget about connection issues.*
Check the recent archives for examples of how to setup pulse to work
with jack. There are several methods. I currently use a script provided
by Fernando Lopez-Lezcano from CCRMA and have configured qjactkctl to
run it at start/stop.
*Apart from on a 64 bit system. Then things can get murky with pulse and
binary apps like skype, flash, real player etc..

I use mplayer for this purpose. It can be compiled with jack support.
