It's possible the hardware (DSP?) does not support interrupts needed for triggering the callback so that function is not implemented. For others with a similar problem if OSS does not work then checkout the dsp wrapper for another sound server, eg, "esddsp" and "padsp" for ESD/PulseAudio resp.

This has been reported a couple of times but did not make it to this list yet, apparently:
A workaround is to force using OSS instead of ALSA using the -vm-sound-OSS option.
