David Baron:
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
