It would be great Csound to support a multi-channel interleaved wave 
file format (for the 5.1 it should be a six-channel file).

I don't know if there is some standardization in multi-channel files 
yet, and, if it is, what is its degree of spread among users and 
developers. For example, AC3 files are not so spread in computer user 
community, and I ignore if they are available free players able to read 
AC3 format and to send the contents of an AC3 file to a real 
multi-channel output in computers having a multi-channel audio interface.

Does the .wav file standard support interleaved multi-channel format? If 
it does, what are the application able to recognize it at present time?

Anyway, it would be nice to have a direct AC3 output support in Csound, 
to make DVDs compatible with most counsumer home-teater systems. Is 
there some open source library supporting this format?

Csound has supported 6-channel WAV for ages, or at least I thought so.  
Richard Dobso is teh expert in this.

Indeed it has. With the move to libsndfile we should get support for 
WAVEFORMATEXTENSIBLE, which is needed these days (for both disk files 
and rendering to a soundcard); Windows will reject multi-channel plain 
WAVE files. The new format specifies speaker positions fo each channel, 
so there is exact support for 5.1 streams.
