Dear experts,

I installed madplay on StrongArm board using ucb1200 device.
I think that the pcm or wav output file is correct, but
when I run the madplay for playing mp3 file, the result is
somewhat weird. I mean, if I play 30 sec's mp3 file with
madplay, the output sound's length is about 28 seconds.
So, the voice's frequency in that mp3 file sounds somewhat
higher than that of the original. Please give me the light
what I'm doing wrong.
The followings are my experimental circumstances.

compiler : arm-linux-gcc (skiff tool chain)
changes : 1) compile with -DFPM_ARM option instead of FPM_INTEL
                 2) change audio device name in audio_oss.c
                     /dev/dsp(audio?) -> /dev/ucb1200
source file : 44100kHz, stereo,(also tried mono file), 128 kbps, mp3

(When I hear the output pcm sound with other tool, it sounds good.
but just only when using madplay for play mode, it sounds some higher
(in frequency) and its play time is shorter.)

Thanks for reading, and any comment will be welcomed.

Best Regards,
bawui
