my first suspicion will go the mp3 backing track you have in there; please try to convert every pcm audio file to a non-lossy and sample-accurate format (eg. .wav, .flac, etc.) and most important that that, on the same exact nominal sample-rate that you normally run your sound-card device (eg. 96k); i believe you can use Audacity for just that.
also, as a rule, it would be a lot better and always preferable to have any re-sampling out of the equation when exporting to audio; so that you shall have ALL audio pcm files encoded in the very same and precise sample-rate--again, that would be the nominal sample-rate JACK (and the DAC) is running--without any chance to drift apart each other when rolling out an audio export operation.
please let me know if there's any improvement in that regard.
cheers
