Oops I top posted. Hopefully this makes more sense. Card is Xonar D1. Source used for testing: http://www.youtube.com/watch?v=e8ODm-F9-IM Tests (repeated for R): (a) - Left visual on video = L speaker (b) - Muted ALSA L channel Master Front = muted L speaker (c) - Muted ALSA L channel Aux = muted L speaker Inputs and tests: Local source (a, b) = OK Line In (a, b) = OK Aux (a, b) = OK, (c) is switched Local source and Line In both work perfectly. Aux works OK iff Aux L and R channels are equal. But adjusting one channel on Aux affects the other one instead. Tested with both arecord and the Analog Input Monitor. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
