I've created an elementary input plugin that plays sound from the
soundcard, so you can use MPD to listen to anything connected to the
line-in jack, or to Video4Linux FM radio cards that send audio through
the soundcard. There has been a small number of posts here in the
past requesting line-in input, so here is a first, simplistic stab at
it.
The patch adds a new sheme, alsa://, which causes mpd to play data
read directly from a souncdard. It defaults to hw:0,0, but you can
pass any ALSA device name in the URI. So, using mpc for example:
mpc add alsa://
mpc play
will play from device hw:0,0.
To use a diffferent device:
mpc add alsa://hw:1,0
