I consulted /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz and a possible fix is to try the following:
edit /etc/modprobe.d/alsa-base, e.g.: gksu gedit /etc/modprobe.d/alsa-base and at the end add add: options snd-hda-intel model=imac-intel or: options snd-hda-intel model=imac-intel-20 I am not entirely sure which of the two apply for your machine, I expect it is the latter, but I suggest trying both out one at a time (e.g. make the change and reboot and check the sound, then try the next option in the same way). This is a required workaround for the sound device having PCI Id 8086:284b. There is an existing wiki page describing this device: https://wiki.ubuntu.com/Gutsy_Intel_HD_Audio_Controller, but it does not have any suitable workarounds listed for your machine. Please let me know if this gets any results. -- No sound on Aluminium iMac with PCI ID 8086:284b https://bugs.launchpad.net/bugs/147087 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
