Hello there!
I have had some problems with sound cards.
In my office I had a Mozart sound card connected to my HP Vectra 486/66
running FreeBSD 2.1.0 (some days ago) and now running FreeBSD 2.1.5.
It did not worked. The kernel did not recognize it as a Sound Blaster. My
card says that it can handle a Sony CDROM. Neither the sound card nor the
CDROM were visible to FreeBSD as you can see in the listing bellow:

Couriously my kernel recognizes some "parts" of my sound card, as you can
see. There is a program called "playmidi" in the packages, and it
reports the sound card is not correctly initialized.
I supossed there was a problem in the card, so I took it to another computer
running MSDOS and it worked perfectly. I made a MSDOS bootable disk and
I configured the drivers of the sound card. I took it to my computer,
installed the card again and made it boot. It worked and the sound card
was clearly functional. Then I pressed Ctrl-Alt-Del and made the
computer start from FreeBSD. The kernel reconize it, as you can see
in this listing:

What happened? I did not know. I shutted my computer down and turned
it off. Again, I boot under FreeBSD and the sound card and my CDROM were
missing again! argh!
But I did not give up. I started again my computer with my MSDOS
diskette and pressed Ctrl-Alt-Del and made my computer start under FreeBSD.
My sound card and my CD-ROM appeared again. I started to cry.
Obviously, MSDOS has made some initilization to my sound card that
was lost when I turned it off. This possible initialization was not
missing when I pressed Ctrl-Alt-Del.
Somehow there was a misterious initialization process in the MS-DOS
drivers that FreeBSD had not made. I think Mozart people can show the
FreeBSD people how to initialize their famous sound card... I will be
very happy if they do.
But as I stated before, I won't give up! If Mozart people do not tell
FreeBSD team who to initialize this card I will hack their drivers and I
will find how to do it!
There is another possibility: perhaps my kernel is not well
configurated. I doubt it. My card works fine under FreeBSD when it is
previously initialized by MS-DOS drivers and rebooted under FreeBSD.
But there is another fact...
In home I have another computer and I bought a cheap sound card called
"Bravo Sound". It claims to be a Sound Blaster clone and it can handle
my Sony CDROM.
It was courious to see the same phenomena with it.
I have a little work to do this days, but the next weekend I promise to
hack the MS-DOS drivers.
I'll keep in touch.
