[Bug 1355984] Re: Built in speakers do not work on iMac 14, 2 and iMac 14, 4
Paul, regarding only the iMac 14,2 could you please test the latest
mainline kernel via http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.17-rc2-utopic/ and advise to the results?
** Description changed:
- No sound from internal speakers but OK from plugged in headphones. Running Xubuntu 14.04 on partitioned iMac 14,4 which has Intel HD Audio (S/PDIF DigitalAudio output). Headphones appear to be using analogue output. Both loud and clear using OSX 10.9.4.
- Have tried all fixes found on many Linux distro websites but no success. Also tried installing Lubuntu (no sound at all) Linux Mint 16 & 17 and Ubuntu 13.04, 13.10 (same problem as Xubuntu).
+ Xubuntu 14.04 on iMac 14,2 no sound from internal speakers. Loud and clear using OSX 10.9.4. Also tried installing Lubuntu (no sound at all) Linux Mint 16 & 17 and Ubuntu 13.04, 13.10 (same problem as Xubuntu).
Have all PulseAudio utils installed, all devices are listed but only analogue volume meter shows outputs when playing but as above nothing from speakers.
AlsaMixer shows S/PDIF (highlighted), SPDIF 1 & S/PDIF 2 not MM, set at 00 but cannot be adjusted.
- What is the problem? I sense there is a simple solution here, if only to ger the analogue output via the internal speakers.
- This is reminiscent of problemsI I had with Unbuntu 12.04 on an earlier iMac which were solved simply using AlsaMixer.
- That I have installed Ubuntu on my new iMac shows how much I prefer Linux to OSX, this small problem is spoiling my enjoyment of your great OS.
- Thank you in anticipation.
- Ed Hughes

- I have the same issue on an iMac 14,2. I think the audio hardware in the iMac 14,2 and 14,4 is probably the same. To get the headphones to work I upgraded to the daily ALSA snapshot found here: https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+packages
- Neither the headphones or the internal speakers work with the default configuration so I did this: # echo "options snd-hda-intel model=imac27_122" >> /etc/modprobe.d/imac_local.conf followed by a reboot. This fix works on every other Mac I have tested so far, but for this machine it only fixes the headphone audio. The output of alsa-info.sh is here: http://www.alsa-project.org/db/?f=08cf13552b70232c96fea9293fdd54066243d79a I have downloaded the HDA Analyzer tool but I can't seem to get the internal speakers to work correctly in any consistent way, although they do occasionally work correctly for a few seconds. I can consistently make sound come from the speakers if I chose VREF = 50 or 80 in Node[0x0d]pin but it sounds like I am using a much smaller lower quality speaker when I do that. Here is the text dump for that node configuration:
