[ale] cdu31a

[andrew1 at onramp.net (Andrew Lancaster)]

I recently built a kernel (2.0) with support for my no-name OPTi mad16-based 
sound card. When I rebooted, the card was initialized and worked fine for 
Doom, but when i tried to play an audio CD(I have a cdu31a drive), it just 
wouldnt work. I then put in an iso9660 disk and tried to mount it, and 
got the error: mount: /dev/sonycd is not a block device. I am fairly sure 
this is not an irq, dma conflict or anything like that, because I built a 
kernel with no sound support, but i still got the same errors( I also was 
careful not to put in conflicting addresses). I did include cdu31a 
support in the kernel each time. The output of dmesg did not have anything 
related to problems with the drive( or anything at all about the drive for 
that matter). One unusual thing I noticed, however is the output of cat 
/proc/devices:
Block devices:
 2 fd
 3 ide0
(the card has a sound card interface, not through ide0, btw) 
This might explain why I did not work even when I removed sound support 
in my kernel, but I haven't been able to explain how this change occured 
or why.

thanks,

p.s. the drive did work before I tried to mess with my sound, and still 
works under OS/2
