Thanks for the explanations.

My AU was not reporting any tailtime. I tried to implement GetTailTime and SupportsTail but I still have problems. I was thinking that as soon an AU has a tailtime, then it would receive silence buffers during the tailtime duration and that would "automatically" clear the last dirty buffer I had. Is the tailtime semantic this one?
Or is there any other way to detect in the ProcessBufferLists method that the AU is in the tail part to call the cleaning code?

Thanks
