Jens - I would be thrilled to get a look at a working play-done callback implementation that works all that way up to the python layer. Any example source you might have would be greatly appreciated. -Shawn Hello Shawn, It turns out I have done this! Well, something close to it anyway. I didn't use a playlist, just a single wav, but it may actually work as-is. I don't have access to the source at the moment though so I'll have to send it tomorrow. I wasn't sure what I did would be palatable to the code owners--not that it is broken in any way, maybe just not as clean as it could be. -------------- next part -------------- An HTML attachment was scrubbed...
