Hi,
currently audioconvert can only convert to different sample formats and
different channel numbers/layouts. In most generic places where it is used
(playbin for example) there is always an audioresample in the pipeline too to
always get something that can be played by the sink.

IMHO we should do the following in the future:
- Move channel conversion and sample format conversion (i.e. float/integer,
different depths/widths, endianess, etc) into separate elements
- Convert audioconvert to a bin that internally plugs everything (i.e. channel
mixing, sample format conversion and resampling) that is require to come from
the input format to the output format. This could of course be more intelligent
than the current "audioconvert ! audioresample ! audioconvert" approach.

What do you think? This could also fix bug #385061 as one could make it easily
use different resampling elements and let it chose the one that makes most
sense or is the fastest or let it be chosen by an environment variable or ...
:)
