What too are you using that's mixing up? the encoder_example that ships
with libtheora should, for example, encode the input wave at the input
number of channels and sample rate.
If you want to use --downmix you can use oggenc to compress the
soundtrack separately and then use oggzmerge to multiplex it with
the video. I assume there's a gstreamer commandline that can downmix
the audio as part of encoding too.
