I gave your recent sound driver a spin and ran into some minor problems
with it on current.
1. The linker set "pnpdevice_set" failed to link. I believe due to the
lack of a tentative definition. I solved this by removing extern from the
declaration in pnp.h.
2. In sound.c, the prototype for "pcmdriver" appears after it is referenced.
I solved this by moving the prototype earlier in the file.
3. In ad1848.c, there is no visible function pointer declaration for
pcmintr.
I solved this by adding a function prototype for pcmintr at the top of the
file.
Now my remaining problems were strictly hardware related. I have a clone
card that claims to be sound blaster 16pnp compatible. It is an Avance
Asound 100.
The pnp info is
CSN 1 Vendor ID: ALS0001 [0x01009305] Serial 0x01000000
I don't know what chipset it uses as the main chip is covered by a sticker
that says only AVANCE. Nor does my motherboard have a pnp bios.
I could get the device partially initialized by having Win95's pnp init it
and
then soft booting into FreeBSD. Windows 95 configures it with the following
ports and interupts.
0x0220 irq 5 dma 5
0x0388
0x0330 irq 9 dma 1
Your driver will recognize it as an sb16 but cat'ing an .au file to
/dev/audio
just results in a 1 second noise that sounds like a hard tap on a
microphone.
Putting the vendor id in as an OPTI in ad1848.c results in a lockup of the
machine with a bunch of "calcru: negative time -24xx seconds" messages.
Putting the vendor id in as a CS42xx gives the following probe messages
after soft booting from windows.
Probing for PnP devices:

I am going to try guspnp15.tgz next and see if that handles it better. But
I thought you should get a little feedback on clone cards with your driver.
