I know how to play a wav file with python_vlc, e.g (here to play an audio stream)
import vlc
instance=vlc.Instance('--input-repeat=-1','--fullscreen')
player=instance.media_player_new()
url="my url"
media=instance.media_new(url)
player.set_media(media)
player.play()
but I didn't find any command to play it in mono mode. Any help appreciated.
I've asked the support of my hardware and searched among stackoverflow questions.
