VLC audio streaming over http

See

https://github.com/piotrbetlej/monit_infrastructure/blob/master/audio_vlc_scr.sh

for working VLC command streaming audio over http. Vlca is just like vlcv a symlink to vlc (making killall on separate vlc process possible).

Hardware is Olinuxino A13 https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-WIFI/open-source-hardware running standard Wheezy (I am cowardly not updating to Jesse because of USB errors seen on BeagleBoneBlack ).
