I beleive you are using the "hacked" dmasound driver for iBook. This
driver can't access any of the sound chip controls. You can't change the
volume, the sample rate, the sample size,... All it can do is blast
samples to the chip via the DMA channel and "hope" the chip is configured
properly. That's why it's a hack ;)
