You can tweak Le Biniou with several environment variables:

The ALSA input plugin always used the default ALSA PCM capture stream. With the LEBINIOU_ALSA_PCM environment variable, the user can now pick another stream, which can be handy in particular ALSA only setups where a user would prefer not to change the default ALSA PCM stream globally.

Usage: LEBINIOU_ALSA_PCM=pcm_name lebiniou -i alsa ... [other options].

You can retrieve the pcm_name with aplay -L.

When using the sndfile input plugin, you can either give a file path with the -a or --audio command line option or with this environment variable.

Usage: LEBINIOU_SNDFILE=/path/file.wav lebiniou -i sndfile ... [other options]

When using the sndfile input plugin, setting this environment variable will make the plugin loop the audio file instead of stopping lebiniou when the end of the track has been reached.
