The software I'm using is Paradise-netrek.  I've tried both 2.0 
compiled and -current compiled binaries.

Here is a code fragment:

*fragsize = 0;
frag = 0x00080007;

ioctl(dsp, SNDCTL_DSP_SETFRAGMENT, &frag);
ioctl(dsp, SNDCTL_DSP_GETBLKSIZE, fragsize);

if (!(*fragsize)) {
    printf ("Error:  Couldn't Get Block Size\n");
}


On Linux (same VoxWare drivers), this code fragment runs through ok.  On 
FreeBSD, the GETBLKSIZE returns 0 causing the Error.
