When I just do kldload/kldunload of this driver (with the card present) I get the following message:
Warning: memory type midi buffers leaked memory on destroy (1 allocations, 16 bytes leaked).

When I have KDE loaded and I do 'kldunload snd_emu10k1' it says 'Device busy'. kinit and artsd have /dev/mixer0 and /dev/dsp0.0 open. But after this after I unload KDE 'kldunload snd_emu10k1' message becomes:
