I was able to fix the problem for the Sndio Output Bundle. I remembered the 
manual page:

http://www.openbsd.org/cgi-bin/man.cgi?query=sio_open&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html

The struct sio_par has a parameter le, which defines the Endianess. Setting this
parameter to LE, makes the sound work again for me on i386 and on macppc.

A patch would look liek this:

Don't know whether other output libraries have the same functionality
to force it to little endian.
