WD TV Mini: selecting Audio side

I have a bunch of RMVB files that are dual audio. Left speaker track has one language and the right speaker track has another language. Is there a way to move the audio gain to the left or right in the WD TV mini? Since it is an analog signal from the WD tv mini, i would not be able to change the audio on the tv side.

Thanks,

If it’s like the Gen1 or Gen2 (which I’ve used) then you can’t. In fact, I’ve never come across any device whatsoever that does this. Has anyone else? This just seems weird to me.
