You can fix this by disabling XMMS's built in WAV reader and using XMMS_Sndfile
instead:

    http://www.zip.com.au/~erikd/XMMS/

which will also allow you to play a large number of other file types.

For reading sound files from within a program libsndfile:

    http://www.zip.com.au/~erikd/libsndfile/

which is required by XMMS_Sndfile anyway. It contains an example program which
uses OSS to play back any sound file it can read.
