I've implemented OS5 streaming sound output. The stream is constantly fed with 11025Hz UInt8 mono data and sounds fine.
However, on Tungsten T3 and Zire 72, the sound is unstable after power off/on (while it's playing) and the app crashes on subsequent exit.
It doesn't do this on other devices; for example, on Tungsten E and Zire 71 it's no problem to cycle the power while sound is playing.
I didn't see any documentation regarding special handling for power off/on. Is there something I must handle to make this work on these devices?
Alternatively, if I'm doing something incorrectly to cause this problem, what could it be?
One thing I do that may be non-standard, is change the A5 register in my callback to access global data while in the callback. (I'm using sme third-party code that is difficult to change and uses a few globals.) Could that be the cause of the problem?
This doesn't seem to be the problem, removing the A5 change does not eliminate the problem.
