Audio dropouts during music playback AFTV2+Kodi

I’ve been trying to figure out why I keeping hearing dropouts when playing music off my NAS thru AFTV2 & Kodi17/SPMC. All video playback is fine, and if I use Sonos to play music off of the same NAS, there is no issue. Is there a buffer limit that can be adjusted in Kodi, or?
