Hallo As You remeber or not I'm developing software driver based on MSVAD sample. My "device"is capture only device. But I have problem. If my driver has both render and capture pins with volume nodes, my topology maps well in SndVol32. I can change volume for all lines, and I can see controls for recording lines. But if I remove render pins and nodes from filters, my topology don't maps properly. In SndVol 32 i can't see any lines for recording. In ksStudio connections and topology for wave and topology filters looks well, but if I select driver from Audio_device category topology has only basic nodes from wave filter. Has anybody the same problem and knows solution ???
