You can't unload a driver if any applications have the sound device open. Why muck around with the kernel drivers anyway? This problem should be solvable in userspace (as long as you don't use /dev/dsp apps). ALSA allows addressing devices by name so module loading order is irrelevant. All that's missing is for .asoundrc to support defining a default device with fallback to another card. Lee ------------------------------------------------------------------------- Take Surveys.
