Hello,

I develop an application using BCB 4 playing PCM data to a soundcard
regularly, using waveOutPrepareHeader and waveOutWrite API. But the
application crashes ("Not responding" of the application, endless looping
may be)after running around half day, when looking at the call stack, it
turns out to be

wdmaud.drv
wdmaud.drv
winmm.dll
msacm32.drv
msacm32.drv
winmm.dll
....

It seems to be deadlock in wdmaud.drv, what are these files used for?? Does
there anyone know the reason why it crashes?? Is there any precautions to be
taken before using these APIs or any method to debug this problem?

Thanks.

Danny
