@IsraelDahl This hw-detect bug can be overcome by just removing the blacklist file
sudo rm /etc/modprobe.d/blacklist.local.conf Reboot. Some users will also have to add snd-aoa-i2sbus to /etc/modules (this is like modprobing the module on startup). If you still have no sound (or more precisely alsamixer doesn't load) then it is likely you are suffering from bug 1066435 . The only way to overcome this is to patch and re-compile the snd-aoa modules. To get your device-id: On a working install (e.g. 12.04) open alsamixer (type alsamixer from a terminal), hit F2, select /proc/asound/cards. Mine is listed as PowerMac Snapper (Dev 38) Sub-frame 0 38 is the device id. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1296373 Title: [PATCH] Fix sound on PowerPC To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hw-detect/+bug/1296373/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
