Could you also post your working MPD configuration under Archphile? It should be in /etc/mpd.conf

Umh let's test this: please disable the FFmpeg decoder plugin in the MPD section (via UI) and let me know if you notice any change with Airplay.

[J@r0d]

Is not OK with disable ffmpeg, sound is distorded with airplay and USB conv

[J@r0d]

I have disable all plugin ffmpeg, etc.... and i have same problem with airplay

I have placed otg_speed in config.txt and i have same problem

Bump, experiencing this issue as well w/ Raspberry Pi 2, USB DAC (Arcam rDac) and RuneAudio_rpi2_0.3-beta_20150304. Can play 16/44 FLAC files without issue but Airplay streams are distorted. Have tried the various suggestions in this thread with no luck.

Found a solution and documented it here
