I've never used xanim, but this behaviour doesn't surprise me. Two things here: 1. Don't forget that there are four channels on the Maestro3 than can be used for playback. /dev/dsp is actaully /dev/dsp0.0, and there is dsp0.1, dsp0.2, and dsp0.3 (along with the dspW variants, etc). I don't think that 4.x makes these extra /dev nodes by default, so you will have to run /dev/MAKEDEV. Yes, the driver will not unload until all channels have been closed. So if you get in a pinch, use another channel. 2. There seems to be an issue where if 'device pcm' is compiled into the kernel and you load snd_maestro3, it will erroneously load snd_pcm. Once this has happened, any attempts to unload snd_pcm will result in a panic. The workaround is to remove 'device pcm' from your kernel.
