It happends rarely and I have never been able to reproduce it.
Sometimes Podium starts to play but no sound is produced.
If I press the stop button it continues. If I press the power off it continues too !
The only way to really stop it is to kill the task.
When I open the same arrangement later it plays fine.
I don’t know if there is some plugin involved, and I cannot send you the arrangements because they have worked normally after.
I think it has happened 3 or 4 times during the last year (multiprocessor is not activated, no other application running together).
Since it has happend today I post this message, but I don’t think that you could guess what it causes it…
