Hi folks,
I am Masafumi, Now leading Japanese Raspberry Pi community and help Japanese Raspberry Pi + Audio community ,which divided from our community. Now Audio community exhibits some use cases with Raspberry Pi at some audio events in Japan and start to help dealing with Raspberry Pi at some audio shop in Akihabara.
For me I tring to make ‘custom Volumio’ to broadcast music to internet (with customized mpd + icecast ) ,almost all work good 
but I have no time to improve because I am extremely busy in management of my Raspberry Pi community.
Hope you all enjoy with me happy Volumio life
