Because, default volume level after driver install on different OSs is different - Seven 100%, Vista 25%. And the main reason - the same value of volume level at different OSs give different gain results. That is why i want to disable volume control to achieve the same sound on sink and source of stream.

If you remove the KSNODETYPE_VOLUME node then a software volume APO will be put in the capture path; there's always a slider on the Levels tab.

These are my MiniportConnections lists. wavtable.h static PCCONNECTION_DESCRIPTOR MiniportConnections[] = { { PCFILTER_NODE, KSPIN_WAVE_CAPTURE_SOURCE, KSNODE_WAVE_ADC, 1 }, { KSNODE_WAVE_ADC, 0, PCFILTER_NODE, KSPIN_WAVE_CAPTURE_SINK } }; toptable.h static PCCONNECTION_DESCRIPTOR MiniportConnections[] = { { PCFILTER_NODE, KSPIN_TOPO_MIC_SOURCE, PCFILTER_NODE, KSPIN_TOPO_WAVEIN_DEST } }; Any type of suggestions?

Please, give me a hint how to disable "Level" tab at properties of this device? Or how to disable volume control of this microphone?Pretty easy, in toptable.h, just remove any node with type KSNODETYPE_VOLUME in TopologyNodes, and/or exclude the node in the MiniportConnections list.
