MY new install of 10.04 was working great on the iMac G3 . I was so impressed, but then my sound stopped working.

I hear the "BONG" at start up but no sound in ubuntu.

Any Ideas?

You might want to add


dmasound-pmac
-r dmasound-pmac
snd-powermac

to /etc/modules

did not work


adding what you suggested means it now looks like this:

snd_powermac
apm_emu
snd-powermac
dmasound-pmac
-r dmasound-pmac
snd-powermac

the last line now appears 3 times.

I found out what is happening with this.

Sometimes on reboot, there is no sound.

If I plug in a headphone then unplug, the sound returns.

This leads me to believe that the autdetection of the headphones is somehow messed up.


Also, I can not install the Gnome Alsa Mixer. ports.ubuntu.com can not be respolved when trying to install.
