The longterm question is if the pysical outputs share a common audio
clock. This does matter when you are feeding them from one program or
just generally with a need for synchronous work.

Are you using mpg123 the command-line program or the decoder library
libmpg123 with your own player code?

If it is the first, there is a JACK output module, built by default if
JACK development files are on the system. You can use it as

mpg123 --stereo -o jack -a Port1,Port2 $your_stream

Doesn't that work for you?


Alrighty then,
