Hello!

I have reproducible annoying problem with 2.1.126ac1,
I can reproduce it only with ESS1868, however (not so much cards
tried however). Can somebody verify that problem really exist not
only for me?

in /etc/modules.conf:
post-install sb /sbin/modprobe "-k" "opl3"
options sb io=0x220 irq=5 dma=1 dma16=-1
options opl3 io=0x388

mordor:~# /usr/local/bin/mixer vol 100
SB 3.1 detected OK (220)
Setting the mixer vol to 100:100.
mordor:~# lsmod

mordor:~# rmmod -a
mordor:~# rmmod -a
Sound device 2 went missing!
This line is printed each time, when sound modules unloads.

All above caused by these 2 lines in sb_common.c, in sb_dsp_unload

if (!sbmpu)
sound_unload_mididev(devc->my_mididev);
However I still cannot find why message above triggered (I mean, I
know why it is triggered, bu I do not know, why this code executes)

Bye,
Oleg
