Comment 8 for bug 1404803

Fixed since https://github.com/mixxxdj/mixxx/commit/40bd85fd63322342a72234bc304fa36db473bbab
by disabling the waveform syncing.
Not sure if it possible to sync again with the effected sound APIs

It currently locks one sync value per deck in mixxx.log maybe we can find a pattern .. of fix it in portaudio.
