It works good, but only problem is a single channel in voice file. Music is ok, I can hear both left and right side well. (and music file is 2 channels).
But, I only can hear left side from voice file. (and voice file is 1 channel).
Are you specifying a mono stream format on the appropriate input element of the mixer? or are you leaving it at the stereo default?
