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 ;) Ben.
