[SlimDevices: Beta] MP3 noise

[Millwood]

Since firmware 66 (I think) i've been noticing pops when I start some
mp3 tracks, or when I skip forward using SongScanner.  But I've seen
similar problems forever.

My mp3's are ripped from internet radio, so they don't start on a frame
boundary.

This is wild speculation - but I suspect that either the server or the
firmware or both are doing a bad job of valid frame boundary
detection.

Its as if sometimes a false sync byte is used.  As I understand it,
finding the sync/frame start byte is an excersize in guessing.  The
more validation, the less likely to use bad data.

As well as the pops, the other indication of this is that slim
sometimes missclasifies the bit rate of my clips.  They play ok, often
after a pop.  Other players (e.g. winamp) get it right.  If I cut a few
thousand bytes off the start of such a track, slim then gets the bit
rate right as well.  So I'm guessing a false frame detect early in the
file was the cause.
