Comment 3 for bug 186341

If I remember correctly, with a Serato record it should take ~20 ms to read enough bits off the record to grab the position. However, that's in the ideal case that your signal is good. If your signal is too weak or is too loud (clipping), it won't pick up the position correctly.

If it's jumping back to 0:30, then it's definitely related to the first problem. I'm not properly adding the lead-in time into my calculations, and it sounds like Mixxx's calculated position (pos. from timecode - Lead-in) is going negative, which is forced to zero instead. (And somewhere along the way it ends up at 0:30...)

Just out of curiosity, what is your lead-in time set at in the vinyl control preferences?

Thanks again,
