Hi, the more recent daily builds for the iPod Mini 2nd Gen aren't playing music at all (for me at least). What happens is you get a few seconds of silence and then a blast of white noise then silence again etc... I checked it with ogg and mp3 files and they had the same result.
I don't have the skills to work out what is going wrong but, for those who do, I went through a bunch of daily builds and whatever is causing it seems to have happened in the transition from 08-30 (works fine) to 08-31 (no music playback).
