Early on I recall reading a lot of comments saying there were audio playback glitches with the rpi. Are these resolved now? I have built 3 or 4 Halloween-related audio projects on Arduino using Adafruit's wav shield and the somo-14d module but they sure are a pain to work with. I would love to do my next project on the pi but was sitting on the sidelines waiting for the early glitches to work themselves out.
