ALSA and 2.4.x

[David van Hoose]

Is there a ALSA backport to 2.4.x anywhere?

Thanks,

ALSA is available to be compiled as module only for 2.4, but the very latest 
version is available for it.

Or if you are using debian, check out alsa packages.

Got it. I patched sound_core.c and I have sound now. I'm assuming that 
was the only file that needed to be patched. Correct? Also, should the 
OSS soundcore option in menuconfig always be 'Y'? It seems to not want 
to be anything else.

I get this warning on almost every file during the compile.
In file included from /usr/src/linux-2.4.21-rc1/include/sound/driver.h:43,
                   from hwdep.c:22:

Another trivial patch perhaps?

Thanks for the patch!

It looks like this is simply a minor include file problem.
sound/sound_core.c needs 
    #include <sound/driver.h>
added to it which should hopefully make this problem go away.

This looked trivial enough to fix, I went ahead and
regenerated my patch with these changes,

Hi !

I add to fix it too, and I sent the patch to Erik privately but it
was not clear that it would indeed fix this problem. It comes from
sound_core.c not including adriver.h which contains the compat code.

Here is a simple patch which works for me.

willy

It compiles for me, but I don't use devfs.  Perhaps there is
a problem with the compatibility code in include/sound/adriver.h

> Can that be fixed?

I am certain it can.  But since it works for me and since I am
moving this week (lots of packing to do) it may not be till sometime
next week before I get the time to work further on it.

Ahh.  Well I don't have any usb audio stuff, so I never saw this
particular conflict.  The old patch is still available under the
/kernel/alternatives directory on my site if you want to use
that patch instead,

I'm getting an unresolved in soundcore.o that is preventing me from 
having sound.
/lib/modules/2.4.21-rc1/kernel/sound/soundcore.o: unresolved symbol 
devfs_remove
/lib/modules/2.4.21-rc1/kernel/sound/soundcore.o: insmod 
/lib/modules/2.4.21-rc1/kernel/sound/soundcore.o failed
/lib/modules/2.4.21-rc1/kernel/sound/soundcore.o: insmod snd-card-0 failed

Can that be fixed?
Also I have problems if I compile USB Audio and USB MIDI from the USB 
section AND USB Audio and USB MIDI from the ALSA section. Compilation 
fails in that situation. Might want to put the former patch up if this 
stuff might take a while to fix.

Thanks,
David

I finally got a bit of time this morning, so I have now updated
my patch set.  I check very carefully and made sure I generated
my ALSA 0.9.2 patch from the correct kernel tree this time, so 
it actually contains my 0.9.2 port this time.

    http://codepoet.org/kernel/

Sorry about having the wrong alsa patch in there last time.  Last
time around I has accidentlly built my alsa patch from my older
alsa kernel tree.  I have this built into my kernel and I now see 

    Partition check:
     hda: hda1 hda2
    Advanced Linux Sound Architecture Driver Version 0.9.2.
    PCI: Setting latency timer of device 00:11.5 to 64
    ALSA device list:
      #0: VIA 8233 at 0xcc00, irq 5

on bootup and xmms is playing.  Hope this is helpful,

Why are you afraid of that?  Yes I am sure it is 0.9.2.  I do
have a 0.9.0-rc6 patch on my site which is derived in part from
your wolk code.  But that is a different animal,

To make my 082_alsa-0.9.2.bz2 patch, I used the wolk 0.9.0-rc6
code, a copy of alsa-driver-0.9.2.tar.bz2, and a copy of the
latest 2.5.x kernel source for reference.  I then hacked on it
for a few hours till I made it work.

    <sound of checking>

Hahaha!  It looks like I copied my 0.9.0-rc6 patch over the top
of my 0.9.2 patch!  Oops.  I still have the source tree where I
hacked together the 0.9.2 kernel patch, so I'll regenerate that
and re-post it after I get some sleep.  <yawns, rubs eyes>

this looks _very_ similar to the patch I had in WOLK4 some time ago and it was 
0.9.0-rc6.

Works *very* well. I now have sound. I'd recommend adding the ALSA 
documentation from 2.5.x to the patch. It is easier than trying to 
navigate through alsa-project.org for setup information. It would be 
nice if ALSA was placed into 2.4.x as soon as possible. Doesn't require 
any extra patches beyond the ones for the kernel.

Thanks for the help!

I was crazy enough to take ALSA 0.9.2 and made it into a patch vs
2.4.x a week or two ago.  I just prefer to have ALSA be part of
the kernel rather than needing to compile it seperately all the
time.  The patch, along with various other things, is included as
part of my 2.4.21-rc1-erik kernel:

This is what I am running locally, and it works for me,
