Bug Description

Using ubuntu 12.04 mac specific amd64 in a 2011 imac 21,5. Sound works on the built-in speakers if no headphone is connected. This is not a audio devide switch mute issue; the sound is activated, but no sound is coming from a regular headphone when it is connected. System is updated and no changes had been made to it.

It also looks to be an ancient bug, which affect macbooks also for example. Let me know which information you need to fix that, and how to obtain that information.

Did apport-collect 1003039; It seems the process was succefull, thought with strange messages on terminal and a black screen with a loading symbol at the last window.

Let me know if it worked or not. Since the above command seems to output results online; if a text file is needed, tell me how to obtain it.

The command worked as intended (apport-collect can give some odd messages even when it succeeds). Thanks for providing the information.

I upgraded my ubuntu from precise to quantal to ensure this bug is fixed at this ubuntu version, as it is the only one(video and keyboard+mouse issues had workarounds) I hadn't found a workaround for my 12,1 imac from the huge amount of information I researched upon. I consider I'm done with research already.

The sound card codec is Cirrus Logic, the snd-hda-intel models for that are imac27 and mbp55, I tried both, which results in internal speaker sound as usual, thought it too gives speaker sound even with a headphone connected to the imac 21,5(the headphone still does no work by the way); the mac book pro and imac 27 have a different number of connectors comparing to a 12,1 imac which have around 9 connectors(counting thunderbolt, headphone mic and output, usbs ans such).

I tried using the latest ubuntu audio packages(throught their ppa, no advanced stuff), updated kernel(only the 3.3.7 stable one works), the snd-hda-intel thing and countless others(muting and unmuting for example).

It seems this issue isnt fixed on Quantal, care to mark this bug as affecting it? Maybe it can get more attention being related to the future ubuntu version(the perfect time to report and fix bugs is now). Also PLEASE let me know of a workaround for the headphones not working at all(just the internal speakers) if you know of any or have the knowledge to devise one.

Exactly the same problem, speaker works well until a headphone inserted, but no sound from the headphone.

Upgraded to Quantal as well, not work.

Thanks to Benzodiaz from ubuntuforums(no help from launchpad) it came to my knowledge which the fix for this already existed since january of this year; being only unused and hidden. Alsa supported codec models for cirrus document was not updated taking in account this 2012 cirrus new model, neither the documentation on ubuntu itself.

Fix for the issue below:
