I have previously used mpd on an older MacPro1,1 with 10.9. The default audio device was detected ok.

I recently upgraded to Macpro6,1 with 10.10 Yosemite

mpd installed without errors, but will not start on my MacPro6,1:

Your solution is the right one. See [https://trac.macports.org/ticket/46861#comment:3] for a detailed explanation. I will make sure output type ao is set in the default mpd.conf to save future new users from similar hiccups.

Will there ever be any alternative to libao? The main drawback is that the audio format is not transferred from the file format (e.g. 24bit 96kHz) to the audio device. You have to go into "Sound MIDI settings" to control this. It would be better if the file format would go unchanged to the audio device. Is it possible to enable this behavior in libao? -- Ticket URL: <https://trac.macports.org/ticket/46325#comment:5> MacPorts <https://www.macports.org/> Ports system for OS X
