Hi! I used the module-assistant tool to build new alsa modules including Micah's patch. Maybe this is useful for someone, so here are the steps involved:
sudo aptitude install module-assistant sudo m-a update sudo m-a prepare sudo m-a get alsa-source sudo m-a unpack alsa-source cd /usr/src/modules/alsa-driver sudo patch -p1 < /path/to/imac91-1.0.18.patch sudo m-a build -O alsa-source sudo m-a install alsa-source The universe repository must be activated, then m-a should take care of the dependancies. After the module is build, the system should be rebooted or all alsa modules reloaded. At least the build and install steps need to be repeated after a kernel update. In the Gnome volume control, channel mode must be set to 6ch. Maybe you need to change volume levels a bit, before sound is actually played. I did not test line in or mic. I used Ubuntu 9.04.

Status in Mactel Support: New Status in “alsa-driver” package in Ubuntu: Incomplete Bug description: I got a new iMac, (version 9,1 March 09). Everything works perfectly except the sound. Sound comes out of the headphone jack. Sound does not come out of the speakers. I've tried numerous fixes, but I think it comes down to the newest iMac hardware not being supported yet. lspci-v 00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1) Subsystem: nVidia Corporation Device cb79 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 15 Memory at d3580000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel modules: snd-hda-intel aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC883 Analog [ALC883 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC883 Digital [ALC883 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 I get the same results in 8.10 and 9.04 _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : [email protected] Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
