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).
With pulseaudio, you can simply use ogg123, and you
don't have to give any special options for ogg123,
just write "ogg123 <1>" and you'll get sound through
jack.
Pulseaudio has amazingly well-working jack audio drivers
and alsa interfaces, so finally linux audio works
without hassle for all programs all the time.
This is the only modification I had to do to make it work:
$ grep jack /etc/pulse/*
/etc/pulse/default.pa:load-module module-jack-source
/etc/pulse/default.pa:load-module module-jack-sink
I don't know how pulseaudio is set up on other distributions,
but on fedora 11 everything seems to work very well.
On fedora 10, on the other hand, pulseaudio sometime started
its own jack daemon called "jackdbus" which hogged
the soundcard but didn't produce any sound, but that's
not the case with fedora 11.
