Thanks Alexander. I think this helps!! =) This is using the laptop's microphone: http://r2d2.webconverger.org/2015-03-04/echotest.mp4 This is closed mic-ed with my superlav+ http://r2d2.webconverger.org/2015-03-04/echotest-with-rode.mp4 I think the levels are still slightly wrong. Also I'm trying to sync or rather delay the audio to match up with the v4l2:///dev/video0 output, but AFAICT the latency adjustments in pavucontrol don't seem to have any effect. Am I missing something? Ñ?паÑ?ибо болÑ?Ñ?ое!
