Fixing manual reset problem for all rendering modules when using a virtual user-triggered sound card. Also adding a VDL before FIR filtering in PrototypeGenericPath to support Doppler shifts, smooth delay handling and sound propagation based on FIR filters for various situations (especially outdoors with fast moving sound sources)
