sound problem ibook g4
Hi I have been using debian squeeze and now sid on a ibookg g4 1.2Ghz which i believe is a late 2004 machine - 30G harddrive.
Some time ago (way before squeeze) sound stopped working at all.
instead I get a scratchy terrible sound that sounds like someone blowing air under their tongue while scratching their fingernails on glass, whenever I try to listen to a ogg or mp3 lecture or music.
When I downloaded a ubuntu live disk 10.04 sound works fine. So it is not a hardware problem.
I had the problem for some before squeeze time and was running squeeze with this problem too. I tried some random things i googled - such as putting snd-powermac in the /etc/modules directory as well as putting
the following modules to be blacklisted:
this had no effect. still the same bad sound.
I upgraded to the latest sid kernel 2.6.38-2
from the squeeze kernel and
no help. I also tried installing the latest alsa-driver from the alsa web site and this did not help?
Is there anything that I can do to get this very portable nice laptop sound working? It worked fine for the longest time...
