Alubook 5,8: No sound with 2.6.17-rc3-g5528e568-dirty

Hi All

First a *Thanks* to all those, here or elsewhere, who spend their time on the development of usable software for PPC Linux: I don't think I ever would have bought the latest alu Powerbook with the option that this machine will be an MacOSX-only one ... :)

As to the reason why I came here:
As I can't be sure whether the issue announced in the subject line is really a kernel issue I put some sound relevant config files in a tarball (~ 12 KB) to my homepage:

wolfgangpfeiffer.com/alsa.configs.tar.gz

In the tarball above you'll find
these local /etc/ dirs with all files below them:
alsa modprobe.d modutils

and these single files, also from /etc/ here:
modules modules.conf pbbuttonsd.conf

The kernel config
http://wolfgangpfeiffer.com/config-2.6.17-rc3-g5528e568-dirty.txt

(Geocities, which my site actually is hosted by, does not allow uploading the file without the file type suffix, IIRC ...)

The kernel, made with non-edited (except the kernel .config), as I hope, git sources, and with the 'make-kpkg' Debian package:

$ cat /proc/version

So with the settings from the files above I run 'alsaconf', and it can't find any sound card:

x                                                          x          
x                                                          x          
x         No supported PnP or PCI card found.              x          
x                                                          x          
x  Would you like to probe legacy ISA sound cards/chips?   x          
x                                                          x          
x                                                          x          
x               <Yes>                  <No>                x          
x                                                          x          

Either answering No or Yes does not help to get sound.

KDE also is complaining. Something like:

---------------------
Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (No such device) The sound server will continue, using the null output device.
-----------------------

The alsapackages seem to be the latest ones I can get:

# apt-get install alsa-base alsa-utils alsaplayer-alsa alsaplayer-common alsaplayer-gtk

alsa-base is already the newest version.

alsaplayer-alsa is already the newest version.
alsaplayer-common is already the newest version.

Did it ever work? I don't quite know what machine a 5,8 is since I have a 5,6 only. Also, try snd-aoa.

johannes

Not with Debian, but with this Ubuntu live CD I have sound:
Ubuntu 6.06 "Dapper Drake" Beta 2 powerpc (20060427)

The kernel on their CD is a 2.6.15-21-powerpc

5.8 is, IINM, the last PPC 15" Powerbook that Apple made

With the git kernel mentioned in my previous mail there's no snd-aoa available, IINM. I'll try figure out how to get the source and compile another kernel with this driver ...

Best Regards
Wolfgang

Hi,

Kind of... with a patch[1] originally by Ben Collins and adapted by Gaudenz Steinlin it at least lets you play your favorite music. The kernel I use is a 2.6.17-rc3-git5.

This patch applied cleanly on every kernel I tried since 2.6.15...

Best regards,
Christoph

[1] http://lists.debian.org/debian-powerpc/2006/03/msg00226.html

Dapper kernel has the hack to consider it as a toonie. No volume control nor anything.

It's not merged upstream yet.

Ben.

Impossible here, it does not compile here. Neither with gcc 4.0 or 4.1

I took your instructions from
http://lists.debian.org/debian-powerpc/2006/03/msg00470.html

And if I understand them correctly it's not necessary to descend to some directory level of the kernel source for my current kernel. I slightly modified your instructions (being addicted to git, Sorry about that ... :) .. :

Something like:

mkdir snd-aoa
cd snd-aoa/
git clone http://johannes.sipsolutions.net/snd-aoa.git/
cd snd-aoa/
make

The above did not work: compile problems:

I should compile with gcc 4.1, IINM:

$ cat /proc/version
 Linux version 2.6.17-rc3-g5528e568-dirty (root@debby1-6) (gcc version
4.1.1 20060428 (prerelease) (Debian 4.1.0-2)) #1 Sun May 7 23:51:15
CEST 2006

Does it help?

Regards
Wolfgang

Not being sure tho' whether the fact my source dir for the running kernel is cleaned up, IINM, (like "fakeroot make-kpkg clean") is the culprit for the failed compile ... I'll have a look into that at next daylight ... :)

Until then

You can't build modules with "cleaned" kernel headers.

Ben.

Hi All

First a fat Thanks to Johannes, Benh and to all of those heroes making it possible to run a relatively freh PPC (Apple) Powerbook model with Linux ... :)

I'm cross-posting. So a short note for those who can't know what all this is about:

I didn't have sound with a fresh git kernel, on the machine mentioned above:

$ cat /proc/cpuinfo 
processor       : 0
cpu             : 7447A, altivec supported
clock           : 833.333000MHz

[Oops, something's messed up there: this actually is a 1.67 Ghz processor. I'll have a look at this later .. :) ]

That's why I sent a message to [email protected]. The thread is starting here:

Wrong. To put it mildly .. :) Result probably of me being too tired, too fast, and too anal when reading instructions ...

# lsmod | grep -i aoa
snd_aoa_codec_onyx     12032  2 
snd_aoa_fabric_layout     7492  2 
snd_aoa                 8076  2 snd_aoa_codec_onyx,snd_aoa_fabric_layout
soundbus                6628  2 snd_aoa_fabric_layout,i2sbus
snd                    60148  12 snd_aoa_codec_onyx,snd_aoa_fabric_layout,
				 snd_aoa,snd_powermac,i2sbus,snd_pcm_oss,
				snd_mixer_oss,snd_pcm,snd_timer   

I successfully compiled the software now, and only with gcc-4.1. Example:

# modinfo snd_aoa 
filename:       /lib/modules/2.6.17-rc3-gf358166a-dirty/kernel/sound/aoa/snd-aoa.ko
description:    Apple Onboard Audio Sound Driver

vermagic:       2.6.17-rc3-gf358166a-dirty mod_unload gcc-4.1
depends:        snd
srcversion:     D0DFD2EF0CFEB8E7C08AAEB

The git kernel I compiled the snd-aoa modules for (must be from about yesterday, IINM):

cat /proc/version
Linux version 2.6.17-rc3-gf358166a-dirty (root@debby1-6) (gcc version 4.1.1 20060428 (prerelease) (Debian 4.1.0-2)) #1 Fri May 12 01:13:36 CEST 2006

config for this latest kernel (Please note the "CONFIG_PREEMPT_VOLUNTARY=y" in there ... :) ... :

<http://wolfgangpfeiffer.com/config-2.6.17-rc3-gf358166a-dirty.txt>

I filled /etc/modules with snd_aoa modules and i have sound already from boot time on ... with a minor glitch (i.e. not being able to store a certain volume level via alsactrl to the next reboot, as it seems), but sound ...

I'm listening to some Internet radio station via alsaplayer while writing this mail ... :) ...

Results, as of now:

I can change the sound volume via the software. Tested in xine and alsaplayer-gtk so far ...

I have problems doing the same with pbbuttonsd. That is I can start, e.g., gtkppbuttons, but when pressing <FN>-<F5> or <FN>-<F4> it seems being impossible to change the sound volume this way. But I can toggle it completely ON/OFF with <FN>-<F3.> ... not being sure tho' whether this is due to some of my braindead mistakes or really a pbbuttonsd issue ...

Thanks again a lot to everyone for your work, your time, and the resulting fine software ... :)

Nice weekend
Wolfgang

No, it's fine, it is clocked down at boot, use cpufreq.

There are a bunch of userland bugs... Alsamixer cannot cope with the 3..28 of the capture volume, some gnome tools can't cope with the negative scale of the playback volume, and others.
I don't want to workaround this, please all file bugs against the respective programs.
amixer always seems to work fine.

No idea, I no longer use pbbuttonsd.

:)

Same as mine, it works fine with snd-aoa

Ben.

I should build a database with a machine string -> user* mapping... This means that even my brother has this one and it works great with snd-aoa as far as I know :)

Though, since the alsa userspace libs absolutely *SUCK* no program I know of can properly represent the mixer controls except maybe amixer... I'd hate to work around this in the kernel, but the alsa libs are such complex beasts that I have a feeling they won't be fixed.

Anyone up to inventing a new mixer API that uses sysfs? ;)

johannes

kmix looks approx. ok
