Guenter, The best you can do is report your position through KSPROPERTIES. If the application that plays your song does not query that information to adjust the play ticker, it was not designed to do so and there is no way you can modify your driver so the application behaves better. The application MUST care about that for the cursor to be adjusted. I'd say you've already done your homework! Out of curiosity, why the heck do you have such a huge latency?

I want to report the current "Play" position to the audio player. I have implemented the properties: KSPROPERTY_AUDIO_LATENCY KSPROPERTY_AUDIO_POSITION KSPROPERTY_AUDIO_LATENCY is never requested, KSPROPERTY_AUDIO_POSITION is periodically requested by the contents does not have an influence to the position bare of the player or to the behavior on the end of a song. Does anybody know which requests must be implemented to handle a sound card with a large latency correctly.
