What might be a jack-enabled equivalent of:
/usr/bin/ogg123 -d alsa <1> (<1> is and ogg file, obviously)
Preferrable would be something that will play through jack if the daemon be
running, alsa not (mplayer can work this way but this is a bit heavy for a
short file play, i.e., a signal from a program).

Try alsaplayer or ecasound
both are can be used for commandline playback of ogg files through jack.

Hi David!
I believe nowadays there's sndfile-jackplay. If sndfile really supports ogg,
it should play this.
Then there's alsaplayer. Despite the name it does do the trick. At least it
did a few years back, when I had it installed.
ecasound can do it, although you might also think it heavy. In any case it
just relies on ogg123.
You might do it with a small pipe. Something like:
oggdec -o - <1> | sndfile-jackplay [whatever options] -
Where "-" of course is stdin/stdout respectively. If you know of more
smalltime jackplayers in commandline mod, I think there was something called
jackplay, you can whomp up those pipes yourself easily.
A last alternative, I can think of, is using the JACK module of ALSa. This
only works, if .asoundrc or alsa's system-wide config is set to include the
jack-plugin as the default output. Then you could use ogg123.
A last question/doubt: Doesn't libao support jack today? If so ogg123 would
work in any case, because it uses libao as output. But as I said, I don't
know.
Kindest regards
Julien

David!
I just checked sndfile-jackplay. It works for ogg. BUT: It doesn't do
samplerate conversions. So you should either lookup jack's samplerate before
and use sndfile-resample (or some other resampling tool) or live with the fact
that some people here your signals at the wrong pitch and speed. Though 44100
to 48000 isn't too bad. Especially if you don't know the original. :-)

MOC (Music on Console) is my favourite command line player. It comes with a
terminal ncurses GUI as well, supports ALSA, OSS, Jack and maybe more, plays
all common audio formats, uses libsamplerate to convert samplerates with high
quality and so on.
The Debian package is called "moc", with /usr/bin/mocp as the binary to not
conflict with moc from Qt.

Hi Frank!
Sorry, completely off the mark: but what is moc from Tt?
It just sounds intriguing. All those similar names (moc and moc, muse and
muse...) :-)
Best,
Julien

moc is the "Meta-Object Compiler" for the Qt widget toolkit. Qt uses
'moc' to implement their signal/slot mechanism. It's like a pre-compiler
or pre-processor. It process a class declaration file (.h, .hpp header)
and creates an implementation (.cpp) for some Qt-specific magic.
MyClass.hpp ---(moc)---> MyClass_moc.cpp--(g++)--> MyClass_moc.o
MyClass.cpp ---------(g++)-----------------------> MyClass.o
It has nothing to do with music.

Thanks Gabirel. I missread a letter there on my braille-display. Should get it
cleaned up and checked. :-(
Warm regards

xmms2 is a media player with core/UI separation and has quite an
extensive command line interface.
Epr is a simple gstreamer media player and can use the jack plugin of
gstreamer.

moc, xmms2 and others are client/server players. A server daemon is loaded and

when the daemon is loaded which is how moc does it.
The command I have above was taken from xringd, a daemon that senses the phone
ringing and can "ring" on the speakers in response. My applet uses this code
in a full telephony applet for a speakerphone modem. SO I need by player-
command to sense jackd at each ring, not just when the daemon is loaded, since
I may or may not be using jack at any time.
If pulseaudio worked, then this should do it. However, jackd is probably
sensed (or required by the suggested configuration) when pulse is started so
it may be little better than moc or xmms2 and this is not a solution or my
applet. KDE's backend utilitlies may also set them selves on startup and be
unchangeable after that.

Preferrable would be something that will play through jack if the daemon be
running, alsa not (mplayer can work this way but this is a bit heavy for a
short file play, i.e., a signal from a program).
mplayer fits the bill perfectly imho and I'm not convinced that it's
that heavy - it actually uses very little memory when just playing a
sound file (mp3, ogg, wave).
If you want a program to have "signal sounds" an external sound player
is bulky regardless of the player used. Jack itself also sounds a bit
overkill. This sounds like the use-case for system sounds, esd, pulse,
etc.

Does anyone have an example of a bash command to check if jack is running?
ex. (untested)
!# /bin/bash
if(jack_connect 2>&1 | grep "server not running")
alsaplayer -i text file.ogg
else
alsaplayer -i text -o jack file.ogg

I agree. Do you want this feature to work so that you can hear the phone
calls when jack is running or do you have a more specific need for
piping the audio through jack?
IIUC the latest version of pulse will use jack if it is running and
reconfigure itself to use alsa directly when it is not running. This is
the point of the dbus code.
However I'm not 100% certain that Kjetils suggested method is the
correct way to achieve this. I was under the impression that the latest
version didn't need to be configured at all. The dbus code in jack2
would take care of the call to reconfigure the i/o sinks. I think
Kjetils suggestion means that jack has to be always on before pa is started.
