I am try to add a peak meter control to an AVStream mixer, with no luck. As per the DDK doc, I inserted the peak meter node as the last node before the capture pin, set the node type to KSNODETYPE_PEAKMETER, and the node name to KSAUDFNAME_PEAKMETER. The node shows up in KsStudio, but it does not recognize the node type (GUID is displayed instead of the node type), and it does not list the KSPROPERTY_AUDIO_PEAKMETER property, just the KSPROPERTY_AUDIO_CPU_RESOURCES property, even though both are supported. The peak meter control does not display using SndVol32. Am I missing something here, or is this a bug? Harry
