ad1848 driver and opl3sa2 cards

[Gerald Teschl]

Hi,

Why does the ad1848 driver try to use the opl3s2 sound card. Is the card 
supposed to
work with this driver as well? Here it does not work since it fails to 
find the card
(isapnp_find_card returns null). Where this is no big deal (one working 
driver is
sufficien;-),  it still causes problems since automatic configuration 
tools like sndconfig
from RedHat will fail, since they use the ad1848 which is the first one 
listed in
modules.isapnpmap:

[gerald@keen gerald]$ cat /lib/modules/2.4.18-4/modules.isapnpmap |grep 
0xa865
ad1848               0xffff     0xffff     0x00000000  0xa865     0x2100
opl3sa2              0xffff     0xffff     0x00000000  0xa865     0x2100

Any ideas? Should the device be removed from ad1848.c?

ad1848 handles the "Microsoft Sound System" aspect, the opl3sax cards are 
MSS compatible. I sent in a patch to fix the detection sometime in 
2.4.19-pre or so, can you try a newish -ac kernel?

This I am aware of, but why has it the YMH0021 listed as supported 
device? Both mss/opl3sa2 mixers
work fine so it looks like everything works ok even tough the ad1848 
does not find the card. So
removing the YMH0021 entry from ad1848_isapnp_list[] should be save.

I would like to do this such that sndconfig can configure this card 
correctly.
Would anybody from RedHat (Bill or Alan) care to comment on this one? If 
you search this and other lists for
opl3sa2 you will see that this will make numerous newbees happy!
