相撲外：Running mpd under Ubuntu 9.10 on a Mac Book Pro 5,2

To run mpd under Ubuntu 9.10 on a MacBook Pro 5,2 make sure that you uncomment the audio_output section in .mpdconf so that it includes:

audio_output {

type "alsa"
format 44100:16:2
}

Otherwise you will get an error in accessing the sound device and sound will not play.
