[KLUG Members] Autoloading sound modules and MP3 playback

[Scott Wood]

Just out of curiousity, do you have the kernel-sources installed for your
current kernel?  If you check under /usr/src/linux/Documentation/sound (using
the symlink for linux-{version} mind you) it has details about the various
sound drivers.  I had to install my Opti card manually just the other night
because sndconfig kept locking up when I tried to probe it.  I later found out
I could get it work by doing a:

sndconfig --no-probe --no-autoconfig

Or something like that anyway - I don't have that machine here and the one here
at work has no sound card so I never installed sndconfig on it.

Sometimes the comments in the various files under:

/usr/src/linux/drivers/sound/maestro.{c,h}

can come in handy too.  Additionally, many of these now tie their functionality
to sb and of course sound_core, etc.  So reading up both the docs and source
comments on those can be helpful as well.

Just as a side note, I see that as of my kernel here at work (v2.2.17) it says
this is a variant of ESS.  The latest version of the driver is said to be
available at:

     http://people.redhat.com/zab/maestro/

It says it should be able to read IO and IRQ information from the PNP support
since it is a PCI device so long as your BIOS (or BIOS configuration) doesn't
prevent it from doing so.

The only parameters is requires are 'debug' for more information on driver
startup and dsps_order=# where # is a power of 2 - apparently this card can
configure up to four distinct dsp devices if desired. ('dsps_order=2' i.e. 2 **
"2"= 4

beyond that, I would guess your conf entries would look something like:

alias sound-slot-0 maestro
options maestro debug dps_order=4

Again, according to the documentation, the maestro "does'n support MIDI or FM
playback at the moment" which means that you probably can't load either the
mpu* module(s) or opl3* either.  But you might try it as it comments about some
cards having an MPU wired to them.  It doesn't say whether they should work.

Hope this helps...
