CONFIG_DMASOUND_PMAC is for the OSS driver. CONFIG_SND_POWERMAC is the ALSA driver. You should not use both, but choose one. Use aumix with the OSS driver, and alsamixer with the ALSA driver.
thanks! that's it. I rebuilt the kernel, making the sound modules built as modules, and load them manually. It works now, except that when playing things with mplayer, the sound is mixed with some irregular voices, the xmms has no such problem. One more question, how can two applications use the sound device at the same time? William
