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
This plugin is cumbersome to support, now that MPD is migrating away
from GLib and the GLib event loop. It has no practical advantages
over the CURL plugin. Soup requires the bloated GType library.
