Thanks! I was right on both counts. The explicit waypoints don't have time stamps at all, so that's why it never shows you the playhead - it's treating the time as 0, which is some time in 1970. And there is indeed an empty track at the beginning of the file. So the fix I released a few minutes ago for tomorrow's build fixes the underlying problem with trying to use the markers in the first place (I just confirmed it works with your file). > I'm on Windows XP, Java version 1.6.0_03, JOSM 574 > > I know its irritating to have ignorant people pontificating and not > doing the programming (I've never programmed in Java), but... > > Is the program structure trying to go against the grain here?

That's almost exactly what's happening now. There's nothing particularly "heavyweight" going on, there's just a single marker in the non-waypoint case to hold the start, and another to sync. I'd need a structure of some kind like that to hold this information, whether you see it or not, so the marker implementation is as good as any in that respect I think. To allow the waypoint case to work properly I still need the markers, and I don't want to change how markers work overall, because it's not just about audio. I also think it is useful to see the sync point specially, though there's no particular reason why audio markers need to be as chunky visually as they are now. > I think the way I would really like to work is to start the voice > recorder and simultaneously make a waymark.

That ought to be fine except that you don't have timestamps on your waypoints. It would work nicely with my GPS, but yours doesn't seem to put timestamps on the waypoints, so it wouldn't work for you - there's no time on the waypo. Maybe there's an option on your GPS for this, or maybe there's an option to name individual track points. I think I could solve this though - if I set unset waypoint times to the first trackpoint time, all would be well. It would also solve the problem of not playing from the start that you had. I can't do that tonight, but I'll let you know when.
