Hi!

I want my NetBSD/macppc box to output some sound. There is no driver for
the awacs chip I have, and it seems writing the driver myself could take
me weeks, if not months. 
Therefore, I purchased a PCI soundblaster (eap), which is supported as a
platform independant driver.

I added
eap*    at pci? dev ? function ?        # Ensoniq AudioPCI 
to my config file, and tried to compile the kernel.

make depend did not worked because of two redefined defines. I had to
patch /sys/dev/audio_if.h around line 156:

#if !defined(__i386__) && !defined(__arm32__)
#define splaudio splbio    /* XXX */
#define IPL_AUDIO IPL_BIO  /* XXX */
#endif 

became this:

#if !defined(__i386__) && !defined(__arm32__)
#ifndef splaudio
#define splaudio splbio    /* XXX */
#endif
#ifndef IPL_AUDIO
#define IPL_AUDIO IPL_BIO  /* XXX */
#endif
#endif 

The make depend worked.
make had a link error at the final stage, because the audio_cd symbol
was missing. I looked for audio_cd in the source tree, and the only
definition is in /sys/dev/audio.c at line 191:

extern struct cfdriver audio_cd;  

I cannot find it anywhere else. I therfore turned the line into
/* extern */ struct cfdriver audio_cd;  

And then the kernel compiled. 

Install new kernel, reboot. It went sucessfully to multiuser, but I
still have this anoying message during boot:

Ensoniq AudioPCI 97 (audio multimedia, revision 0x08) at pci0 dev 17
function 0 not configured

Question is: how to get a soundblaster to work in a macppc? did anyone
ever tried this?
