[Gumstix-users] AFMT_S16_BE problem

[Brad M. <bmi...@xm...>]

hi

hope this doesn't appear as a dup

fyi, I think the ioctl below should fail (or be fixed in the kernel, or 
we should switch to alsa kernel driver)

big-endian audio comes out as static but little-endian audio works.

     int format=AFMT_S16_BE;

     if((audio_fd=open("/dev/dsp",O_WRONLY,0))==-1) {
         perror("\nFile open error\n");
         exit(1);
     }
     if(ioctl(audio_fd,SNDCTL_DSP_SETFMT,&format)==-1) {
         perror("\nioctl no. 1\n");
         exit(1);
     }

once i realized this, i managed to get stereo audio reception basically 
working on my gumstix. it still needs performance tweaks--there are 
pauses in the audio and the cpu gets warm, but at least it seems like 
everything is there for stereo reception.
