View Full Version : No sound on Fedora : Imac PPC

8th March 2009, 08:44 PM
Good evening,
I have a problem with the sound of my computer.
I have got a imac G4 PPC (the sunflower !) and try Fedora 10. I upgrade my kernel element but I don't hear anything more, even though the pulseaudio or alsa volume meter/alsamixer are ok and show a variation.

I don't know how to solve this problem. thanks a lot for your help.

My configuration is :

I try with my headphones, pulseaudio move but no sounds !


9th March 2009, 10:16 AM
Moved to Mac & PPC...

9th March 2009, 02:04 PM

I work in gnome desktop essentially, but i may work in KDE too.
I have the both environnment.

I've tried some tools and I have always the same results:
- Totem, rhythmbox, Gnome Mplayer, Amarok, VLC
- I've no sound at all : system, music and video
- I've no difference of behaviour between gnome and kde.

Thanks for your help

sorry bud, i've moved on to Ubuntu... but i got my audio to work after i updated.

Good evening,

It's an idea but I don't think so for the moment. I'll try Fedora (I'm pretty obstinate :)).
Did you have something special to do on with your speakers on Ubuntu ?

Thanks for the response

No, worked "out of the box".

12th March 2009, 12:20 AM
I assumed so with my mac, but it's more complicated than I imagined.
There's no recognition of my speakers nor headphones.

Very curious !

You need powermac snapper. I had the same problem when I tried Fedora 10. The easiest way for me was just to get an older version of Fedora, install and upgrade to ten. I know it is not the way they recommend but I must have sound.

I've tried Ubuntu, Kubuntu, Opensuse and tried installing Debian Lenny but had no luck with it. I've found that Fedora works best for me on my 12 inch G4 powerbook with 764 mb of ram. It is the only computer I have.

There are things that I wish Fedora did better with 10. I get the loading/lib/kdb/keymaps/i386/qwerty/us.maps often when I reboot my system. It is a pain in the neck rebooting over and over till I get past that. I wish that Fedora 10 for PPC would install with powermac snapper like the other versions did. If something works why break it is how I feel. I tried testing the alpha for 11 but it would not install. Regardless of that problem Fedora beats the other distributions for me.

So the lesson I learned yesterday was stick with what you know, which in my case was Fedora. I mean wireless works for me, flash using gnash, streaming tv sites, ibm java for java games since other does not. Totem I love that youtube plugin where you can watch youtube videos from it. I wish KDE had a plugin like that for a movie player. But till it does Totem is my movie player though I use KDe 4 desktop.

Good evening,

You're right : after doing :
modprobe snd_powemac , the driver was loaded and then I have sound with "powermac snapper".
Nevertheless :
- i've had a warning :
'modprobe warning : /etc/modprobe.d/sound line 1 ignoring bad line starting with snd-aoa'

- after 2 minutes when I switch the volume, I lost the signal.
- After reboot, I must do it again in order to have sound. There was no autoload.

If you have new brilliant ideas, I'm interested in !!

Thanks for lot

Good morning,

up !!

16th March 2009, 08:21 PM
The way sound stayed all the time for me was by installing an older version of Fedora and after that updating 10. I don't know why powermac snapper is not there by default like it was before.

Good evening,

I had the same problem under Fedora 9, that's why I've upgraded to Fedora 10.
But, there's probably a little tips to do, but I don't know what.

Hi I run Debian but this may work? run run as root

alsactl store

this is meant to store sound setting maybe it's the same in Fedora?

I installed Fedora 7 first put in Fedora 10 chose upgrade and had my sound. Never tried 8 or 9. Since pc people need it not sure why they the distributors take it out.

Pulseaudio should be called pulseaudio hell from the threads I have read on other distributions besides this one.

17th March 2009, 03:30 PM
Good afternoon,

Well we could call pulseaudio like this, but it may be very useful when it works. :p

Hi oswaldkelso, I'll try this evening and I'll tell you.

Yeah when it works. Just my opinion but it seems every distribution rushed so fast with pulseaudio.

If oswaldkelso suggestion works put fixed in the title. Will have to try it also if it does.

18th March 2009, 01:08 AM
Good evening

I'll try and we'll see.


19th March 2009, 12:50 PM
Good morning,

I'm always here.
Because of all my difficulties, I decided to remove alsa and pulseaudio in order to reinstall cleanly. So I did before going to office.
And after a very long time, it reboots and :
- a recurrent message :
Loading lib/keymap/i386/azerty/fr-latin9.map .
I must wait for a while
- A bottomright kernel error window which sends a mail to X
- and after all, I had a different login window on a white/grey background (and not the usual blue sun), very ugly with a unknown logo as an X ou K (I don't how to describe this). Problem : None of my login and pwd works !! even as root.
So nice, isn't it ?
I'll try again this evening and, pray..


19th March 2009, 02:02 PM
Ok, I know, it can sound just stupid, what I'm going to say, but it was my experience installing Fedora 10 on a PowerMac G5. The sound was not working - and I thought, damn, it's again the same problem as in Fedora 9. Then I tried to load the snd_powermac module. Still nothing. After reinstalling (for other reasons!) I discovered that I had just to adjust the Volume Control in Gnome - by default it was muted.
Therefore check it, if you haven't done it yet.
This just to say, that pulse audio worked on that machine.
After that I would try loading that module 'modprobe snd_powermac'

19th March 2009, 04:33 PM
Good afternoon,

Well I had sound for 2 minutes and after reboot nothing. So I know that sound is possible.
Did you do something special in order to have sound automatically after reboot ? I mean after the modprobe.

Thanks for your answer,


19th March 2009, 06:11 PM
If loading the snd_powermac module is working for you, than you should tell to the kernel to load it at startup. In Debian you do it adding the name of the module to the file /etc/modules (as root).
I do believe, that you can do the same in Fedora, but I'm not sure and I can't check it right now.
Do you have that file /etc/modules? If yes, do it.

19th March 2009, 11:30 PM

bad luck today, I can't reboot.
This special window refuses all login and password I give. Or as user, it seems to load and then shows me the same window.

With ctrl+alt+F2, terminal mode, I can log but I don't know how to start on my desktop.

I try to reinstall alsa, but the response is "no more mirror to try" so I can't download and install it. I assumed that the reason is 'no web' !!

If you have a brilliant idea, please help me !!! :eek:

20th March 2009, 12:43 AM
Strange... At the first 'login window', that it says that the name or the password are incorrect, or what?
Did you change anything in your configuration?

20th March 2009, 01:15 AM
Nothing. I just uninstall pulseaudio and alsa.


25th March 2009, 10:59 PM
After this choice, what a disaster !!

I couldn't boot, or more precisely I had the weird window. So I've reinstalled F10 on my mac with KDE desktop.
I have the same problem of sound but I can boot...
Back to departure !
