Hi Praphan,
First off, take it that I *know* that you know your stuff very well. So, it can't be about that. Therefore you must take the few remarks below as the positive input to what could be going on really. Okay ?
The only setting that I can get PA engaged is to set "fade out step" to 0.
Totally impossible that this is related.
and the other new feature within PA to 0 too (sorry cannot remember the name
"After SFS Rounds".
This can be true, but if all is right, only visually (*~* stuff). Of course, when you set your SFS to 430 and SFS Rounds to 9, then PA will never engage for the first track.
What is far more likely, is that something is incurred for which is related to XXEngine3.exe being in memory all the time, and a reattempt of Playback does strange things, unexpected by me and your usage. Or ... what about you have left it in memory at upgrading to 0.9z-7-3 ? That would be highly incompatible. There's a check in the "install" to throw it out, but maybe that doesn't work properly, or you did not upgrade to a new folder. Anyway ...
When the latter is not in order, please focus on re-attempting playback. So, when you see strange things, first kill the sound engine from memory (click on the blue led in the right) and start playback right after that (quite harmless to Memory Allocation if you don't wait 30 seconds).
All IOW, in *that* area things "drastically" changed and mistake can have been made easily by me. Still I don't have any problem myself, so the chance that this is it is unlikely.
Activation stuff *is* likely as well as applying the "upgrade" is, like I just talked about ...
Let me know what you find !
Regards,
Peter
