Well, this is the log of the so called X-server. Responsible for the
graphic output. The X-server has nothing to do with your sound.

The Debian installer should recognized your sound card. Please post
the output from (done within a terminal):

$ cat /proc/asound/version
$ cat /proc/asound/cards
$ lsmod | grep snd

You can try (as root):

,----
| rmmod snd_aoa_i2sbus
| rmmod snd_aoa_soundbus
| modprobe snd-powermac
`----

See if it works and reportback. If that doesn't work, then (also as root):

,----
| echo snd-powermac >> /etc/modules
| shutdown -r now
`----

(This will reboot your notebook)

If one of the above works, then it will be one point more for the
installer not to install the snd_aoa* drivers by default.

This is a very old version. We're just uploaing 1.0.21. Well if you
upgrade to at least squeeze (testing) xour chip should be recognized
from the kernel.

The correct driver for your tumbler should be snd-powermac. Do as
root:
# echo snd-powermac >> /etc/modules
# reboot.

Just for the record, I'm including here people from debian-boot, so that
this extra piece of information gets somehow included in future versions
of d-i (if it is not incorporated already).

Nice, great. Really great that it worked. I'm leaving most of our
discussion here for reference of people at other mailing lists.

Right, but now the snd-powermac driver is what is being used instead of
the snd-aoa* driver.

Perhaps BenH (one of the principal developers of Linux on PowerPC) could
shed some comments here with the final word so that we can settle this
snd-aoa vs. snd-powermac for the time being.

Basically, I just told you to load one driver for the sound card that
was more likely to work with your hardware (which is more or less
similar to mine) than the driver that was being loaded by default.

> ill try to find out on manuals.

To learn a little bit more about what I told you to perform, you can
read the following manuals:

,----
| man modprobe
| man rmmod
| man insmod
| man lsmod
| man 5 modules
| man shutdown
`----

(You should have the man-db and manpages packages).

> you want any other report?

No, thanks. That's fine for now (unless you have another problem).

The correct machine ID is probably PowerBook3,3.

Ouch

I've been avoiding the sound stuff like a plague since the Apple stuff
is a total mess

If aoa works generally better on this machine then the distro should use
it by default. I was somewhat hoping somebody would take over those
sound drivers once for all but they seem to systematically scare off all
the volunteers we can find

Sadly, I don't have the time nowadays to do much work on them myself.

Cheers,
Ben.

Do you know a way for us to know if aoa or powerpc is the right
choice? Or the oposite, a way to know that aoa is known to be broken
in a set of machine ids or like?

Well, generally speaking, aoa only picks up machines it knows about no ?

Actually, no. Since I have been building my own kernels, I have no
problems with snd-powerpc.

OTOH, many people on -powerpc has sent messages along the lines "I
just installed lenny/etch/squeeze/foo on my {Power,i}{Book,Mac} and I
can't get any sound, is there anybody here that can help me?".

It seems that on some G5 machines, snd-powerpc could cause some lock
ups, but the problem was reported ages ago and it seems to have been
fixed. I'm not sure if Charles Plessy (in CC) still has his dual G5
and can test it, but I seem to recall that he once had the problem
and, months latter, tested it again and didn't find any problems with
snd-powermac.

(Is this correct, Charles? My memory seems to be failing me lately.)

So, for a distribution kernel, I guess that, once nobody complains
about the problems, we can just standardize on snd-powermac (and have
people have a working setup) and document the potential (perhaps
nonexistent?) problem in the release notes for the arch.

I am willing to learn a bit about the kernel, but I don't have
knowledge about hardware.

Opinons?


Regards, Rogério Brito.

P.S.: Ben, are there low-hanging fruits in the kernel for PowePC on
Macs?

Helo Rogério and everybody,

I have indeed made a test last year on an iMac G5, and did not experience lock
ups anymore, so I think that the problem is solved on that side.

By the way, I have returned the now old dual G5 to the computer service at my
workplace and will not be able to make tests on it anymore as I am now using
the amd64 port on Intel hardware now. I still have the iMac G5 at home, and it
is used by somebody else. Linux is still bootable, but unless nobody else can
do tests, I would prefer not taking risks by making new installer tests. I have
updated the following wiki page accordingly (by deleting my name).

Have a nice day, and thank you very much for your dedication to this port !

Completely agree with that. snd-aoa was made for newer Macs AFAIK, and
it works very well here. The one that cause problem here is a
powermac3,3 which is an old model, and which is not supported by snd-aoa
according to http://johannes.sipsolutions.net/Projects/snd-aoa

I am CC'ing Johannes, he may help us solve that long standing problem.

Regards,
Benjamin

In this case we ought try to find a way to "detect" those machines and
add support for hw-detect to properly queue the require module based
on that.

I'm sorry, I don't exactly know the current problem, but here on
debian-ppc we keep having (as Rogério noted) people having problems with
snd-aoa getting loaded instead of snd-powermac, as far as I understand.
A quick search in my archives gives me the following threads :

http://lists.debian.org/debian-powerpc/2009/09/msg00059.html
http://lists.debian.org/debian-powerpc/2009/08/msg00009.html
http://lists.debian.org/debian-powerpc/2009/06/msg00034.html
http://lists.debian.org/debian-powerpc/2009/05/msg00096.html
http://lists.debian.org/debian-powerpc/2009/02/msg00083.html

Just for 2009. I thought you could help, as there don't seem to be a lot
of people left here that have the knowledge to solve that, appart from
saying "try modprobe snd-powermac". I think people on this list would be
gratefull if you could help.

Regards,
Benjamin
