strange problem with an AWE ISA card

strange problem with an AWE ISA card

[Roberto De Leo]

Hi,
I know this is the developers list but this problem is really odd and it 
seems to me it fits better in this ML.

Here is the problem. I am the author of the eMoviX package, a micro 
Linux distro that makes a CD able to boot and autoplay [with MPlayer] 
all audio/video files it contains.
My hw autodetection system for ISA cards makes use of 
/proc/bus/isapnp/devices but it failed for a user which has a SB AWE 
card. He claims that in the devices file his card is identified as 
"CTL00e3" but in the cardids.txt file that code does not appear anywhere!
I have access to a PC with a similar card and for it I get the code 
"CTL00e4" that is perfectly good.

How come that not all SB AWE card models are supported?
What is, more or less, the percentage of ISA cards covered by cardids.txt?
At this point I need this info since if the percentage is far from 100% 
I'll change hw autodetection system.

Thanks,
  Roberto De Leo

Note that we have "generic" entries for sb awe cards for a long time in 
our CVS. They ignore the card id. Look to alsa-kernel/isa/sb16.c.
