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

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

timebase        : 8320000
platform        : PowerMac
machine         : PowerBook5,8
motherboard     : PowerBook5,8 MacRISC3 Power Macintosh 
detected as     : 287 (PowerBook G4 15")
pmac flags      : 00000019
L2 cache        : 512K unified

[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 linuxppc-dev@ozlabs.org. 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,

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

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 ... :) ... :


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
