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: pcm0: unregister: channel pcm0:play:dsp0.p1 busy (pid 39136) pcm0: unregister: mixer busy pcm0: unregister: mixer busy pcm0: unregister: mixer busy pcm0: unregister: mixer busy pcm0: unregister: mixer busy pcm0: unregister: mixer busy pcm0: unregister: channel pcm0:play:dsp0.p1 busy (pid 1578) pcm0: unregister: channel pcm0:play:dsp0.p1 busy (pid 1578) pcm0: unregister: mixer busy kldunload: attempt to unload file that was loaded by the kernel kldunload: attempt to unload file that was loaded by the kernel kldunload: attempt to unload file that was loaded by the kernel kldunload: attempt to unload file that was loaded by the kernel pcm0: detached Warning: memory type midi buffers leaked memory on destroy (1 allocations, 16 bytes leaked). >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
