Hi Takashi

Adrian: this was one of the cards you listed as having an OSS but not an 
ALSA driver a while ago.

Attached you'll find an ALSA driver for AdLib FM cards. An AdLib card is 
just an OPL2, which was already supported by sound/drivers/opl3, so only 
very minimal bus-glue is needed. The patch applies cleanly to both 
2.6.16 and 2.6.16-mm1.

The driver has been tested with an actual ancient 8-bit ISA AdLib card 
and works fine. It also works fine for an OPL3 {,emulation} as still 
found on many ISA soundcards but given that AdLib cards don't have their 
own mixer, upping the volume from 0 might be a problem without the card 
driver already loaded and driving the OPL3.

As far as I am concerned, this does not need additional testing and can 
go to alsa-kernel after a review. It's very unlikely that anyone still 
has this ancient card installed anyway. The one I have here was lent to 
me and will be returned shortly, but given the minimal nature of this 
driver, maintenance should not be a problem.

I also stuck a very tiny HOWTO in ALSA-Configuration.txt, assuming quite 
a few people would have no idea how to operate the thing, even if they 
do happen across a card. Is it okay there?

Takashi: As the card->shortname, I use "AdLib FM", which includes a 
space. sound/core/init.c:choose_default_id() goes to lengths to not 
allow this (it turns it into "FM") but when I manually give:

   modprobe snd-adlib id="AdLib FM" port=0x388

then the ID is used as is and everything seems fine. I assume that 
either the space check could go or that a passed in ID should be 
subjected to it as well? (that function also deletes all !isalnum's from 
the shortname such as <underscore> which, again, is fine when passed in 
manually).

Comments appreciated. I'll go listen to this AdLib render "Master of 
Puppets" again now. Heavens, what fun...

Rene.
