I'm using Qt2.3.10 and QSound class to play a wav format file on my embedded arm devices.

QSound:lay("/home/sound.wav");

My question is, why after I run my program no sound can be heard?

./myprogram -qws

Is there any configuration that need to be added?

My wav file format is : RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 8000 Hz

Thx..
