Bug Description
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.
To get the headphones to work I upgraded to the daily ALSA snapshot found here: https:/
The output of alsa-info.sh is here: http://

Don't know if this is helpful or not, but I found this in my syslog:
