[sdlsound] alt audio converter

[torbjorn.e.andersson at tietoenator.com]

The alternative audio converter still needs a min() function to compile. Of
course, that's trivial to add. (More seriously it still doesn't seem to work
very well, even for the simple conversions I tried, but I haven't had the
time to figure out why yet.)
