No sound on Fedora : Imac PPC

juanalan · #1 8th March 2009, 07:44 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 :

Moved to Mac & PPC...

juanalan · #4 9th March 2009, 01:04 PM

Hi,

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.

juanalan · #6 11th March 2009, 11:11 PM

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

juanalan

Captain Fazekas · #7 11th March 2009, 11:14 PM

No, worked "out of the box".

juanalan · #8 11th March 2009, 11:20 PM

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 !!

carlfriend1 · #12 16th March 2009, 07:21 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.

juanalan · #13 16th March 2009, 09:32 PM

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

Code:

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.
