Note that we currently hack the sunaudio plugin to calculate the single-gain
and balance from the two stereo gains.  However, due to rounding errors, this
sometimes causes the sliders to act a little wonky.  Part of the problem is
that the GStreamer gains go 0-100 while the SunAudio gain goes from 0-255 and
the balance goes from -32 to +32.  So converting between these different ranges
is part of the reason for the rounding errors.

To give an example of what I describe as "wonkyness", if you slide one gain
around, the other gain wiggles up and down a little.  It might be possible to
minimize this sort of wonkyness by making the calculations a bit smarter, or
caching the last values and compensating.  But it would still be nicer if
GStreamer worked either way.
