a) "-acodec libmp3lame -f mp2"
I think MP3 audio in an MP2 container (which is a "raw" MP2 audio
container) shouldn't work, even though ffmpeg happily muxes it.
b) "-f mp3"
You are streaming raw MP3. This may or may not be fine for your
Barix box. According to Barix documentation, this should work.
Said documentation seems to show how to configure CBR 192 kbit/s,
but says the device can handle "all frequencies/bitrates".
Perhaps you should just try "-c:a libmp3lame -b:a 192k -f mp3 [...]".
You could also try RTP.

Is it? Then why do you spread it all around the internet?
