HI:
I have installed the Angstrom system on beaglebord and I did some
audio coding.
Atfer some work, aplay music.wav finally worked. I programed using
ASLA API such as snd_pcm_writei(handle, data, wcount) and so on to
play a wav-file, the code worked on the beagleboard-XM revB too.I
can
hear music from headphone.
But when I used another kind of audio coding:
fd = open("/dev/dsp", O_WRONLY);
......
write(fd, buf, wcount);
......
It didn't work on beaglebord, there was no sound from headphone.
Does the beagleboard not support this kind of audio coding or I
should do some configuration to make /dev/dsp
effective.
Ask for your help.
Best wishes!
