For newer powermacs (including G5 and some G4) snd-aoa (http://johannes.sipsolutions.net/Projects/snd-aoa) seems to have taken over frm snd_powermac. but according to the reply to http://ozlabs.org/pipermail/linuxppc-dev/2007-May/035089.html it does not (yet) support older g4 powerbooks yet. in a private email johannes has said "I don't think such old machines use snd-aoa. Try find /proc/device-tree -name layout-id if something shows up snd-aoa may be to blame, otherwise you need to use snd-powermac." "find /proc/device-tree -name layout-id" returns nothing on my PowerBook3,5 -- No sound in linux-image-2.6.20-8-powerpc G4 https://bugs.launchpad.net/bugs/87652 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
