Re: Sound and BCM4318 wireless no longer working in Wheezy on late 2005 G5
I had exactly this problem with an ibook G4 (i.e. the sound - no issues
with wireless etc.)
I fixed it by going to /etc/modprobe.d/ and removing all the snd-aoa module names from the list in alsa-blacklist (the file has some similar name; I'm not on that machine so I don't have it just now). I then removed snd-powermac from /etc/modules and rebooted. I got a mixer etc. working then. I also installed pulseaudio, but that may or may not be required.
I found the suggestion to do this here:
https://wiki.ubuntu.com/PowerPCFAQ#Why_do_I_have_no_sound.3F
There are a few other suggestions there, they may also help.
The incorrect blacklist appears to have been introduced recently, which would explain why the upgrade caused the problem.
