Timing & Callbacks

Hi,
if I select two different devices in my audio application, there are clicks appearing in certain periods, about 10s. The application is a realtime effect processor passing audio from input thru effect to output.

Thinking about principles of input and output callbacks, if we have two different devices, the clock is never so accurate to make the count of input and output calls to be the same, and it causes these clicks. This will not occur in one driver/multiple card solutions, where the timing may be synchronized in driver, but I am searching for a general solution.

Is it possible to solve this problem by means of CA API?

Lubor, DSound
