Problems with wavread on 64-bit linux box

When reading wav file on 64bit Fedora wavread reports problems; same wav file can be opened with wavread without any problems on a 32bit platform.

Version: GNU Octave, version 2.9.9 (x86_64-redhat-linux-gnu).

'uname -a': Linux host.domain.com 2.6.22.4-65.fc7 #1 SMP Tue Aug 21 21:50:50 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

'file test.wav':
test.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 16000 Hz


wavread reports
octave:1> x=wavread('/data/tmp/w-data/original_mono/test.wav');
error: wavread: sample format 0x3e80 is not supported

wavread will read the same file without any problems on a 32bit box.
