I think this is what happens (I haven't tested): if you have non-aux channels on the sound card, let's say front-left, front-right, rear-left and rear-right, and you try to loop back just rear-left and rear-right, the resampler (which really takes care of more conversion than just sample rate) will try to be smart and mix some of front-left and front-right into the rear-left and rear-right channels. The same logic is involved always when a stream - be it capture or playback - is connected to a device that doesn't have the same parameters as the stream. Configuring the device to use aux channels should disable the "intelligent" remixing - only the channels specified by the stream will be taken from the source. -- Tanu
