Re: State of sound support in 2.3.x

I have the 2.3.52 kernel from Paul's tree, with PowerMac DMA
sound support compiled in.  I guess my question is:  what is the
current
quoted
state of sound support in Paul's 2.3.52 kernel?
My primary distribution source is also LimuxPPC.

Geert Uytterhoeven posted a patch to split the DMA sound support between
Pmac, Atari etc. a while ago (look for dmasound split).
Okay, I applied the patch (and the patch to the patch) that I found in the
list archives.  It built fine, but upon reboot, sound doesn't work at all
(no beep even).  I tried building both Sound Support and PowerMac AWACS
support as modules, and it produced one module called soundcore.c.  I
rebooted with this kernel and insmod'ed it, and it still doesn't work,
although /dev/dsp and /dev/mixer existed this time.  Any clues?  I've got a
UMAX S900, which, IIRC is a 9500 clone.
Yes (I think) - I should have posted a patch for this.

in drivers/char/mem.c there are two areas in which calls (and its
declaration) to init_dmasound() are conditional on CONFIG_DMASOUND - but
CONFIG_DMASOUND has been removed.

You need to change those lines to something like...

#if defined(CONFIG_DMASOUND_AWACS) || defined(CONFIG_DMASOUND_ATARI....

or whatever (the various CONFIG_DMASOUND_XXXXX are visible in the Makefiles)

Sorry about this - I was very new to the list and carried out some of the
discussion without doing cc's ;-)

I think that is it - basically you have everything complied in - but it
isn't being called at init time.

Iain.
