Hello All,

I am trying to use multimedia timers for audio synchronization.I am trying
to get
event every 20 ms so that i can fill up the audio buffer for the driver
to play.I wrote a  test app to see how the multimedia timers work.I am
trying to
print the time intervals . when i start other applications on vista
the timing interval gets affected.It shows 26, 45 ms etc even though it is
set to 20ms.
Pls let me know why its happening so if anybody have idea.Can we depend on
multimedia timers
for the events for the audio applications.
