you're not doing anything wrong but using crappy MP3 files :)
it's a known (very) old issue with MP3 files only: depending on the encoding (VBR are the worst in that regard), there's very little chance you get a sample-accurate mp3 stream. truth is, it isn't, never were, never will.
there's no fix in the horizon for that--MP3 (libmad) support is being deprecated and will be phased-out any-time sooner or later. as a matter of fact, most linux distros don't provide libmad (or any other mp3 codec packages), mostly due to licence and patent legal issues, then letting users rely on third-parties for that matter.
you're then strongly advised to use FLAC (lossless) or Ogg Vorbis (lossy).
