Environment Variables
You can tweak Le Biniou with several environment variables.
LEBINIOU_ALSA_PCM
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 ....
You can retrieve the pcm_name with aplay -L.

When using the sndfile input plugin, setting this environment

track has been reached.
