If it would be possible with ALSA someone would already done it. 
Back to the topic. In audacious in the audio settings select alsa and click on 
the settings button again. Now you should get a selection window where you can 
select different output devices. 
For clementine this is not directly possible as it is using the global 
gstreamer settings that can only be setup with a gnome gstreamer settings 
module I am afraid. 

And again this would be a nice feature to have but its impossible with alsa 
this way. For this you need something like pulseaudio and pavucontrol.
