External Audio Track in Zoom Player won't skip

[Beave]

When I use an additional audio track in Zoom Player (beside 2 internal tracks) the external audio track always starts to play from the beginning. It is not possible to jump to a specific time in the timeline.
It worked before. Maybe some newer version broke that or is something wrong with my setup here?

The external track support is a complete hack, I don't think I touched the code that supports it for at least 8 months.
