Documentation for CMI 8330 (SoundPRO) 
-------------------------------------
Alessandro Zummo <azummo@ita.flashnet.it>

( Be sure to read Documentation/sound/oss/SoundPro too )


This adapter is now directly supported by the sb driver.

 The only thing you have to do is to compile the kernel sound
support as a module and to enable kernel ISAPnP support,
as shown below.


CONFIG_SOUND=m
CONFIG_SOUND_SB=m

CONFIG_PNP=y
CONFIG_ISAPNP=y


and optionally:


CONFIG_SOUND_MPU401=m

 for MPU401 support.


(I suggest you to use "make menuconfig" or "make xconfig" 
 for a more comfortable configuration editing)



Then you can do

 modprobe sb

and everything will be (hopefully) configured.

You should get something similar in syslog:

sb: CMI8330 detected.
sb: CMI8330 sb base located at 0x220
sb: CMI8330 mpu base located at 0x330
sb: CMI8330 mail reports to Alessandro Zummo <azummo@ita.flashnet.it>
sb: ISAPnP reports CMI 8330 SoundPRO at i/o 0x220, irq 7, dma 1,5




The old documentation file follows for reference
purposes.


How to enable CMI 8330 (SOUNDPRO) soundchip on Linux
------------------------------------------
Stefan Laudat <Stefan.Laudat@asit.ro>

[Note: The CMI 8338 is unrelated and is supported by cmpci.o]

	
	In order to use CMI8330 under Linux  you just have to use a proper isapnp.conf, a good isapnp and a little bit of patience.  I use isapnp 1.17, but
you may get a better one I guess at http://www.roestock.demon.co.uk/isapnptools/.

	Of course you will have to compile kernel sound support as module, as shown below:

CONFIG_SOUND=m
CONFIG_SOUND_OSS=m
CONFIG_SOUND_SB=m
CONFIG_SOUND_ADLIB=m
CONFIG_SOUND_MPU401=m
# Mikro$chaft sound system (kinda useful here ;))	
CONFIG_SOUND_MSS=m

	The /etc/isapnp.conf file will be:

	The module sequence is trivial:

/sbin/insmod soundcore
/sbin/insmod sound
/sbin/insmod uart401
# insert this first
/sbin/insmod ad1848 io=0x530 irq=7 dma=0 soundpro=1
# The sb module is an alternative to the ad1848 (Microsoft Sound System)
# Anyhow, this is full duplex and has MIDI
/sbin/insmod sb io=0x220 dma=1 dma16=5 irq=5 mpu_io=0x330



Alma Chao <elysian@ethereal.torsion.org> suggests the following in
a /etc/modprobe.d/*conf file:

alias sound ad1848
alias synth0 opl3
options ad1848 io=0x530 irq=7 dma=0 soundpro=1
options opl3 io=0x388
