I tried my microphone settings: 1. Set to Microphone Array (Conexant Smart Audio HD), I can record (video conference) but it recorded my background noise even I muted my microphone on conference software , VooV. 2. Set to Stereo MIx (Conexant Smart Audio HD), I can record but the other audience not able to hear what I say even I unmuted my microphone. How can I record without picking my background noise (when I am muted ) ? Many thanks
